Evaporating extrasolar planet does a lot of controversy


Dutch astronomers have found strong evidence see that a road falls apart standing exoplanet from. A New will analyze NASA's Kepler observations-Satellite planet shows that, in less give 16 hours to be running star, is covered in large amounts of dust from his planet surface loose. Result for accepted publication in astronomy & astrophysics.

Kepler looking to other nearby planets years to our stars give sun, called exoplanets.
If for some exoplanet host star rotates along, obscuring it one of the very little starlight. By the light of more hundred thousand stars give you may Kepler monitors rare planetary transitions detect it in population example of other stars planets around capturing.

Kepler has recently mysterious object found with the prosaic name KIC 12557548, with or quantity obscured starlight varies John of other transition to. Been suggested possibility hereby or to a given planet goes slowly falls apart. A New , analyze detailed Kepler data will now clearly shows that planet during transition or scattered by the large amounts of starlight that go planet dust originates.

"KIC 12557548 job runs in a very short around its parent star" says Matteo Brogi (University of Leiden), the First article author. "Because he is so close to its star is, the surface planet goes very hot, about 2000 degrees Kelvin. This gives very strong movements in the innermost planet go, leading to widespread volcanism. Part of Dust's compartment INS Fri Heat evaporates quickly go through or star. The fumes of the substance lead to variations or embezzlement in or from earth we perceive "concludes Brogi." We Can spectroscopy meth go now investigate the matter "continues coauthor Christoph Keller, "to understand you go in for that composition Speed planet if he loses mass".
