Astrophysicists working together, and a team of researchers has clearly, a giant extrasolar planets are its central star distortion and destroyed – this discovery could help to explain this star called WASP 12b – why the abnormal shape of the planet.
This discovery may explain WASP 12b – not only on what happened, also mean scientists obtained a unique opportunity to observation a planet to enter the final stage of the life it. The study of the cooperation, Beijing great subject dimension Daniel Astronomy and Astrophysics research Institute (Kavli Astronomy for Astrophysics and population), at the university of California ShengKeLuZi LinChao professor said: “this is the first astronomer witness a planet is collapsing.” and death Kewei Daniel days and the institute of astrophysics in Beijing university is a new research institutions in this research, the main job. They in 2010, feb. 25 issue of the journal nature published the findings.
The study’s lead author lee express Lin was still in kewei Daniel astronomy and astrophysics research institute graduate, she is analyzed and a team of this planet, prove the observed data of the star attraction to this planet “side, accelerate the bloated” it rapidly process.
Found in 2008 – the WASP 12b is outside the solar system in the past 15 years found more than 400 planet most difficult to understand. It around the block of a quality and the sun is shipped stars. And most of the known extrasolar planets, WASP is a huge 12b – the gaseous planet in the solar system, with the Jupiter and Saturn some similar. Different in that it is in extremely close to rotate around the star in the distance, the star, the average distance to only 1/44. Another odd shape, it is more than the size of the prediction model of astrophysics. According to estimation, and its quality is only about 50%, how Jupiter is 80%, radius is almost six times! It is abnormal, the side facing star scorching temperatures exceed 2,500 degrees Celsius.
The researchers think that there must be some mechanism makes this planet expansion to the extent such unexpectedly. They focus on the analysis on the tidal forces that WASP 12b – on the tidal forces strong enough to produce the effect of various views.
In the earth, the earth and the moon between ocean tides force and two day. However, the WASP star 12b – very near, so from this planet tidal forces will be very great, even completely changing the shape of the planet, from the spherical became close football shape.
The tidal forces will not distort the shape of the planet. Through the continuous changes of shape and planetary tidal forces will also cause friction within the planet. The friction heat, causing the planet to inflation. LinChao professor said: “this is the first direct evidence to prove that the planets, internal heat (or” tidal heating ‘) can make this planet to the size of the present.”
The researchers said that although the WASP 12b – but it is very huge, facing the fate of die early. In fact, excessive swelling “is one of the trouble. Due to the excessive inflation, the bodily form with the planet has not the Lord star gravity retaining their substance in ping-pong. Lee express Lin explained: “the WASP 12b – 60 million tons in the second to the central star erosion rate at this rate and quality. This planet in a thousand years in the epicenter was totally eclipsing stars. It sounds like a very long time, but the astronomers, this time is very short. This planet earth now only for the life of the age of 1 in 450.”
12b – from the material loss WASP not directly, but fell into the star in a star formation, hovering around slowly into the host. 12b orbital motions of WASP – the thorough analysis shows that this dish is there another star quality smaller planets in the disturbance of its orbit. This planet is likely to be a massive planets — known as “the earth”.
This planet material plate and included in this super earth, all can be used to detect the existing facility. They will help us to further clarify the nature of this mysterious WASP 12b – the history and fate. Planets,
