Hot exoplanets atmosphere structure

New studies about exoplanets atmosphere structure

The first results of the analysis of eight hot planets showed that the structure of the atmospheres of these exoplanets  is more difficult, than was considered earlier. Catharine Hitson from University of Exeter, England, delivered the report on carrying out this research on the National astronomical assembly which was taking place in Saint Andrews, Scotland, on July 5. Hot planets represent huge exoplanets the size approximately about Jupiter. The exoplanets address in such short distance to the stars that the atmospheres of these planets are warmed to 1000-3000 degrees Celsius. Astronomers can find what gases are present at the atmospheres of hot planets, analyzing a range of the star light which has passed through the atmosphere of a planet when a planet is directly before a disk of the star.

As a result of carrying out the large review of eight hot planets researchers opened unusual properties of the atmospheres of these planets. First, in the atmospheres of the heated giants it wasn’t revealed titan dioxide, which had to play a role of peculiar ozone layer of hot planets. Besides the titan dioxide scientists found out water vapor in the atmospheres of two of studied planets that became important confirmation of scientific theories dominating now on a structure exoplanets of this type.
