摘 要：The search for extrasolar planets has resulted in the discovery of super-Earths, with masses less than ten Earth masses. Regarding the orbital distances, some of these planets are very close to its star, at distances much less than Mercury to the Sun. Since no such planets exist in our solar system, the atmospheres of these hot rocky planets remains largely unknown. In this work, we present the main characteristics of this hot rocky planet population, with a focus on the potential atmospheric composition obtained by assuming different types of planetary composition and using corresponding model calculations. The vaporization of silicate magma is used in order to explore hot atmospheres above 1,000 K. We present how to estimate the range of atmospheric compositions for rocky planets for different semi-major axis and show an application of the results, to the Kepler February 2011 data release. Our model suggests that hot, rocky super-Earth atmospheres can be divided into five types, whose definition is strongly dependent on the initial composition and the planet's distance to the star. These simple set of parameters provided, can be used to explore atmospheric compositions for current and future candidates provided by the Kepler mission and other searches.
