三つの会社：スターのトリオを周回する新しい検出の惑星


新たに発見された惑星は非常に奇妙な天体に配置され、一度に星3を周回発見されました。

「惑星が星を周回されている - このシナリオでは、単独の星を、「ケビン・ワグナー、アリゾナ大学での最初の年に博士課程の学生は、Space.comに語りました。惑星や星はAはその後、科学者が「スター・B」と「Cでの星を（システムの軌道ダンスのビデオを表示するには、以下のチェック）を呼び出し星のペアを周回します。

奇妙な新しい世界では、HD 131399Abは、星座ケンタウルス座で、地球から340光年の場所に位置しました。システムを介してその軌道の約半分は、空に見えるすべての3つ星。 【奇妙なエイリアンの惑星（ギャラリー）]
何が3つ星をHD 131399Abの誰かのように見えるでしょうか？スタッフSpace.comのいくつかの予備的な計算は、すべての3つの星は地球上の満月を見て午前中に類似するであろうことを示唆しています。

HD 131399Abの場合には、星は太陽よりもはるかに大きいと明るくなる - 約80パーセントより大きく、7.8倍明るいです。しかし、惑星の約2倍の距離である、約82天文単位（天文単位は太陽に地球からの距離であり、9300万マイルまたは1.5億キロ）の距離で星を周回します太陽から冥王星までの平均。距離の増加は、太陽が地球上で私たちに表示されたときに星がHD 131399Ab上の観察者にのみ、約0.00116倍明るく見えることを意味します。満月は、それがまだ空で支配的な存在になることを意味し、地球から見えるようしかし、星はまだ明るいように、約464回表示されます。

その他の比較は：地球はちょうど日没後であるとして冥王星の表面には、午後の高い日は、多くの光を持ち帰りました。オープンHD 1313388Ab、星Aは約2倍多くの光を提供します。

スターBとCは、星のAをBよりも小さいと調光器である日ほど明るく、わずか約0.87倍であり、同じ質量について持っています。 Cは、日（約60パーセント太陽の質量）よりも小さい質量の星であり、唯一の0.17倍明るいです。 （その軌道の惑星の位置に応じて300から400天文単位）地球からはるかに大きい距離で周回するこの2つ星。その結果、彼らの最も近い惑星に接近し、星は地球上の満月の約3.86 B倍の明るさを表示されます。そして、Cの星は、満月の約0.75倍の明るさを表示します。

"、550地球年持続する、惑星の軌道の約半数では空に見える3つ星、2は一緒にぼやけている、と分裂の変化は星から明らかです年間を通じて明るい、「ワーグナーは声明で述べています。 「長年の惑星については、[3]の星は、毎日3つのユニークな日の出や日没の夜ためにそれを身近で昼側を与え、近くにまとめて表示されます。惑星の軌道と星のように毎日外のさらなる発展には、彼らは1のセットは、[他の2]の立ち上がりに一致点に達した - 。今回は惑星が約四分の一のためにほぼ連続的に昼間にありその軌道、または約140地球年」

惑星の最大の軌道は、これまでに発見された - 3つ星のシステムの別の態様は、驚きの科学者をどのように星の周りの惑星の軌道の大きさがあり3つ星のシステムは、ワーグナーはSpace.comに語りました。また、BとCの星は、彼らがしていることを星の重力Aに非常に近い軌道」地球のために非常に重要な、 "ワグナーは言いました。遠く離れた他の2から3の他の星系、スターに非常に近い軌道を回る惑星、そしてより多くの、で、彼は言いました。

「この[3つ星のシステムは]私たちが今までこのようになりますことがわかりました最初の一つである、「ワーグナーはSpace.comに語りました。 「それは、多くの可能性と思っていたよりも惑星は、複数の星系で、はるかにエキゾチックな構成で存在し得ることを示しています。」

太陽系外惑星ハンター

練習ハンターを見て、他の惑星の技術的保護とは対照的にHDは、望遠鏡で直接見られるように、惑星からの光を直接撮影と呼ばれる技術を用いて検出すること131399Ab間接的な手段を通じて洗練。

高度なスペクトロ高コントラスト偏太陽系外惑星インストゥルメント・リサーチ（SPHERE）と呼ばれる直接描画ツールを使用して、天文学者は惑星が約1070華氏（580度であることを発見しましたC）とは直接最も寒いと最も撮影外惑星の一つとなって、約4木星の質量を量ります。研究者はまた、その大気中の水とメタンを発見しました。

SPHEREは、チリのアタカマ砂漠にある超大型望遠鏡ヨーロッパ南天天文台に搭載されたデバイスです。 SPHEREは、それが他の隠された太陽系外惑星の熱シグネチャを検出できることを意味し、赤外光に敏感です。このツールは、具体的に順番に、大気のぼかし効果を修復、あなたのイメージのコントラストと地球の質量を増加させるために補償光学と呼ばれる技術を使用しています不要な星明かりは、ワグナーが説明する、新しい研究の筆頭著者です。

「HD 131399Abが直接撮影されたいくつかの系外惑星の一つであり、それはとても興味深いキネマティック構成で最初の一つである、「ダニエルのApaI、天文学の助教授とUA惑星科学は、声明の中で述べています。

で、約16万年前、HD 131399Abも最年少の太陽系外惑星の一つは、サイエンス誌に本日（7月7日）発表された研究報告によると、これまでに発見されました。

3つ星のシステムを実装する方法

本研究の研究者は状況古典的な星形成に形成されたシステムを決定しているが、大半は元の、それ自身の重力で崩壊した巨大分子雲で始まります惑星の謎のまま。

「可能なシナリオは、それが星のAの周りされている可能性があり、ディスクに形成されていることがあり、システムを形成した後、「ワーグナーはSpace.comに語りました。

しかし、冥王星ので約二倍の距離が私たちの太陽系の太陽からのものである、地球のために利用可能な材料の多くが形成された取得することはできません。

"だから、私たちは惑星が実際に星の1に非常に近い形成されていると思います。そして、いくつかの分散液または移行を通じて、惑星は、現在の行を周回することが判明しましたそれは、「ワグナーは言いました。

次に、研究者は、システムの長期安定性を決定するために、運動や惑星の軌道をテストする予定。

"我々は、それが安定だと思うが、私たちは確かに言うことはできません、「ワグナーは言いました。 「安定した軌道は、惑星の数軌道内に通常調整されます。それは内にある場合、それは惑星を調整するために多くの時間を持っていますので、システム自体は、1600万歳安定軌道。しかし16万年はかなり若いですので、それは安定した軌道上に配置された場合、それは驚くべきことではないでしょう。今、私たちは本当に言うことができません確かに、ので、我々は唯一の軌道上のどこの惑星のスナップショットを持って、それが完了するまでに500年以上かかりました。」

Three's company: planet orbiting around a star trio new discoveryNewly discovered planets are placed in a strange celestial bodies, at the same time discovered orbiting stars 3."Star has been orbiting the planet-in this scenario, the single star," in the first year by Kevin Wagner, University of Arizona doctoral student, told Space.com. Planets and stars a then scientists and star B "stars in C (to reveal the system's orbital dance video, following checks) pair call stars around.In a strange new world, HD 131399Ab, in the Centaurus constellation from Earth 340 light years away where was located. All of the system through half its orbit looks in the sky 3 stars. [A strange alien planet (Gallery)]What are three-star HD 131399Ab someone looks like? Preliminary calculations of Space.com staff saw the moon on Earth all three stars indicate will be similar in the morning.HD 131399Ab for the stars than the Sun much brighter and larger-about 80 percent larger, 7.8 times brighter. But, at a distance of about twice the planet approximately 82 astronomical units (astronomical unit Sun and at a distance from the Earth 93 million miles or kilometers 150 million) of average to Pluto from the Sun orbiting the star at a distance. Means that looks bright 0.00116 times, only by the observer on the HD 131399Ab stars when increase the distance of the Sun appears to us on Earth. Full moon, it is still however and meant to become a dominant presence in the sky as seen from Earth, stars, as it's still bright about 464 appears twice.Other comparisons: took home more light, higher in the afternoon on the surface of Pluto, and the Earth just after sunset. Open HD 1313388Ab, A-star is approximately 2 x provides more light.Dimmer with the stars B and C are less than a star, so bright and just about 0.87 times and has about the same mass. C a day (about 60% solar mass) is less than the mass of only 0.17 times brighter. (Depending on the positions of the planets in their orbits 300 to 400 astronomical units) to orbit at a much greater distance from the Earth, the two stars. As a result, close to their nearest planet and star shows the brightness of about 3.86 B times the full moon on Earth. And the stars C displays the brightness of about 0.75 times the full moon.", 550 Earth to last year, looks empty in about half of the planet's orbit 3-star and 2 blurred together, and is a division of star is clear bright throughout the year," Wagner said in a statement. "On the planet for many years, [3] stars daily night three unique Sunrise and sunset for the day by giving it close, close together appear. Orbits of the planets and star daily on the further development of the outside they 1 set to rise in the two other match points amounted to-. This planet and in the daytime almost continuously for about a quarter of its orbit, or about 140 Earth years.Largest orbit of a planet is discovered-3 is another aspect of the star system and the size of the orbit of a planet around a star how to surprise scientists, the three-star system, Wagner told Space.com. Also stars B and C is that they're A star's gravity very close to going "very important to the Earth," Wagner said. Planets orbiting very close to 3 other star systems, stars from the other two far away, and many more, in, he said."This [three star system, in the first one we found that we should ever look like this," Wagner told Space.com. "It is thought more likely than planet is multiple star systems, shows that exist in much more exotic configuration. 」Extrasolar Planet HunterTo detect using light from the planet is called direct shooting watch Hunter practice, as opposed to the technical protection of the planet's other HD is directly seen in the telescope as refined through 131399 Ab indirect means.Advanced spectrogram high contrast eccentric extrasolar directly drawing tool called a planetary instrument research (SPHERE), astronomers planets around 1,070 degrees Fahrenheit (found at 580 degrees C) and direct the coldest and most taken out weigh about 4 Jupiter masses, is one of the planet. The researchers also discovered that atmospheric water and methane.SPHERE is a device mounted on the very large telescope European Southern Observatory in Chile's Atacama desert. SPHERE, it has other hidden outside of solar system is sensitive to infrared light, which signifies that can detect the heat signature of a planet. This tool is specifically in the order in which the atmospheric blur need Starlight is using a technology called Adaptive Optics in order to increase the contrast of the image of the repair, you and the Earth's mass effect to explain the Wagner, is the lead author of the new study."Out of some HD 131399Ab was taken directly one of the planet as it is, one of the first interesting kinematic configurations in" Associate Professor Daniel ApaI, astronomy, and the UA Planetary Sciences says in a statement.The 160000 years ago, HD 131399Ab is the youngest Exoplanet discovered so far and one of the planet, according to a study reported in the journal Science published today (7/7).How to implement the three-star systemThis study researchers determine the formed situations a classic star-forming system and remains a mystery begins with a giant molecular cloud collapsed under the gravity of its own, the original planet's majority."There could have been A star around it is a possible scenario, have been formed on the disk and then formed a system," Wagner told Space.com.However, you cannot get many of the materials are available for the Earth was formed, with Pluto from the Sun in our solar system is about 2 times the distance."So I think our planet is actually very close to one of the stars are formed. And some dispersions or migrations through the planet, circling the current row determined that it was "said Wagner.Will the scientists to determine the long-term stability of the system to test motor and planetary orbits."We think it is stable, but we cannot say for sure," said Wagner. "Stable orbit is usually adjusted in the number of orbits of the planet. Because it has a lot of time to regulate the planet it is if it is in the system itself was 16 million stable orbit. You wouldn't 160000 quite young but so is it arranged in a stable orbit, it is not surprising. Right now, we can't really say that, indeed, took more than 500 years, we got a snapshot of a planet in orbit only where it will be completed. 」

Three of the company: new discovery of planets orbiting the star of the trio newly discovered planet is placed in a very strange celestial bodies, has been orbiting discovered stars 3 at a time. "Planet is orbiting the star -. In this scenario, a single star," Kevin Wagner, a student of first year doctoral program at the University of Arizona, told the Space.com planets and stars a then, scientists with the "star · B," "star of in the C (to view the track dance of the system video, the following check) will orbit the call star pairing. strange new world in, HD 131399Ab is, in the constellation Centaurus, it was located in the place of 340 light-years from Earth. through the system is about half of its orbit, all three stars appear in the sky. [strange alien planet ( Gallery)] What would seem a 3 star like someone of HD 131399Ab? some of the preliminary calculation of staff Space.com, all of the three stars in the morning to see the full moon on the earth we suggest that would be similar. in the case of HD 131399Ab, the star becomes brighter and much larger than the sun -. greater than about 80 percent, it is 7.8 times brighter, however, of about 2 times the planet is the distance, (the distance from the Earth in astronomical unit is the sun, 93 million miles, or 150,000,000 kg) about 82 astronomical unit is the average. distance increased from the distance to orbiting the star sun to Pluto, the sun there star when it is displayed to us on earth is only the observer on the HD 131399Ab, means that you look about 0.00116 times brighter. full moon is, it that is still the dominant presence in the sky meaning and, as seen from the Earth, however, as the star is still bright, will be displayed for about 464 times. other comparison: Earth in just Pluto of the surface as is after sunset, is high the day of the afternoon, a number of offers a brought back the light. open HD 1313388Ab, star a is about twice as much light. star B and C, the a star as bright as is the day a small and dimmer than the B, only about 0.87 times, we have about the same mass. C, the day is a small mass of the star than (about 60% of solar mass), it is the only 0.17 times brighter. (depending on the position of the planets that orbit this 2-star orbiting at a much greater distance from 300 to 400 astronomical units) Earth. as a result, close to their nearest planets, stars will appear the brightness of about 3.86 B multiple of the full moon on the earth . and, star of C shows the brightness of about 0.75 times that of the full moon. ", 550 sustained Earth year, three visible in the sky at about half of the orbit of the planet star, 2 are blurred together , and changes in the division is bright through the clear annual from the star, "Wagner says in a statement. "For many years of the planet, the star of [3], given the dayside a familiar it for three unique sunrise and sunset of the night every day, it will be displayed close to the collectively. Planets orbit the star is to the further development of the outside every day so, they are first set, reached match point to the rise of the [other two] -. almost continuously during the day for this time the planet is about one-quarter Yes its orbit, or about 140 Earth years ", the largest of the orbit of the planet, so far has been found - another aspect of the 3-star system, orbit of the planet around the how the star scientists of surprise It is of there is a size 3-star system, Wagner was told to Space.com. In addition, star of B and C, they have to be star gravity A very close orbit "very important for the earth to of the are," Wagner said. Far away the other 2 from 3 of other star systems, planets orbiting very close to the star, and many more, in, he said. "the [3-star system] is that we will in this way until now is the first one of which was found, "Wagner told the Space.com." it's the planet than I thought a lot of possibilities, in multiple star systems, may be present in a much more exotic configuration shows that. " extrasolar planet hunter technology look at the practice hunter, and technical protection of other planets as opposed to HD, as seen directly through a telescope, called directly photographed the light from the planet refined through 131399Ab indirect means can be detected using. Using a direct-write tool called Advanced Spectro high contrast polarized exoplanet Instrument Research (SPHERE), astronomers directly with (C, which was found to be 580 degrees) planet is about 1070 degrees Fahrenheit become one of the most photographed outside the planet and the most cold, it weighed a mass of about 4 Jupiter. The researchers also found a water and methane in the atmosphere. SPHERE is a device that is mounted on the Very Large Telescope European Southern Observatory in the Atacama Desert of Chile. SPHERE is, it means that you can detect the heat signatures of other hidden extrasolar planet, it is sensitive to infrared light. This tool, in specific order, repair the blurring effect of the atmosphere, we use a technique called adaptive optics in order to increase the contrast and the earth of the mass of your image unwanted starlight is, Wagner description to, is the lead author of the new study. "HD 131399Ab is one of the few exoplanets that have been taken directly, it is the first one in a very interesting kinematic structure," Daniel of ApaI, assistant professor and UA planetary science of astronomy, of the statement users had said in the middle. in, about 16 million years ago, is one of the HD 131399Ab also the youngest of the extrasolar planet, today in the journal Science (July 7, 2008) According to the published research report, it found so far has been. 3 star of how to implement the system huge researcher of this study is to determine the system that has been formed in the situation the classic star formation, but most of that was destroyed in the original, its own gravity while the beginning and the planet mystery molecular cloud. "possible scenarios, after it may have been around star a, may have been formed in the disc, to form a system," Wagner I was told to Space.com. However, a distance of about twice in the Pluto is from the sun of our solar system, you will not be able to get a lot of material available for the Earth has been formed . "so, I think we are formed very close to one of the planet is actually star. Then, through some of the dispersion or migration, the planet, is it to be around the current line was found, "Wagner said. Then, the researchers, in order to determine the long-term stability of the system to, plan. to test the trajectory of the movement and the planet is "we, but I think it's stable, we can not say for sure," Wagner said. "stable orbit, the number of planets is usually adjusted in the track. If it is located within, because it has a lot of time in order to adjust the planet, the system itself, because the 16 million-year-old stable orbit. But 160,000 years is quite young, it is when placed in a stable orbit, it would not be surprising. now, we can not really say for sure, because, we have a snapshot of only where the planet in orbit , it took up to more than 500 years to complete.

Detection of three companies: new planet around the star TrioThe newly discovered planet is a very peculiar celestial bodies are arranged at one time was discovered orbiting a star."The planet is wrapped to the stars in this scenario, the lone star," Kevin Wagner, in the first year, a Ph.D. student at the University of Arizona. Space said. Planets and stars A, scientists B "Star" and "star of C displaying system of orbital dance video, check the following) calls around the star.A strange new world, Ab HD 131399 in the constellation Centaurus, from Earth at 340 of light years. Through the system of its orbit about half the sky, all three stars. The strange alien planets of GalleryYou"ll see what someone HD 131399 Ab 3 stars? The staff Space some preliminary calculation of all three stars in the morning to see the full moon on the earth with similar to suggest that.In the case of HD 131399 Ab, stars and the sun will be far more than the big bright than about 80 percent, 7.8 times brighter. However, at about twice the distance of the planet, is about 82 astronomical units (AU) in the sun, and the distance from the earth 1.5 193 million kilometers or miles) from the sun to Pluto will average around stars in the distance. The increase of the distance from the sun on the earth, our only to look up the stars in the HD 131399 Ab about 0.00116 times brighter means. The full moon in the sky, it is still a dominant means to be visible from earth, but still as bright stars in the times about 464.Comparison of the other: on Pluto"s surface and the earth is just a day after the death in the afternoon to go high, a lot of light. Open HD 1313388 Ab, star A offers a lot of light is about two times.Star B C as bright as day, and in the light of the stars A is smaller than B regulation, and only about 0.87 times the mass of the same. The C (about 60 percent of the mass of the sun) is smaller than the mass of the star, the only 0.17 times brighter. In accordance with the position of a planet orbiting astronomical unit 300 to 400) far from earth orbiting in the distance the two big stars. As a result, the access to their nearest planets, stars will display the brightness of about 3.86 B times on the earth. The C 0.75 star, about double the display brightness.Where the earth to 550 years, 3 stars in about half of the planet"s orbit, sky, blurred together, and the change of the division is clear from the bright stars throughout the year, "Wagner said in a statement. "Years of planets, stars, [3] every day to day side to close it for sunrise and sunset night three unique, close to you. The development and the orbit of the planet of the star that additional outside every day, set, they reached the rising edge of the other two match points. This time its orbit in the daytime is almost continuously for one quarter of the planet earth, or about 140 years. "The planet"s orbit, the largest so far found on three different aspects of the system, the science of how amazing is the size of a planet in orbit around a star three star system, Space Wagner said. The B C star, and they are very important to be very close to the star A orbit of earth gravity "," Wagner said. Other star systems from the other of the distant star very close orbit around the planet, and more, he said."This is one of the three stars in our system so far in this way can be found of the first one, Space Wagner said. "It"s a planet than I thought possible, a plurality of many star systems are far more exotic structure that can exist."The outer solar system planet huntersWatch Hunter practice, in contrast to other planets HD technical protection, as seen in the sophisticated telescope directly through indirect means 131399 Ab is detected by using a technique called directly from planet to shoot the light.インストゥルメント・リサーチ planets outside the solar system polarization spectrometer with high contrast, high SPHERE) directly using the drawing tools, astronomy
