The search for rocky exoplanets plays an important role in our quest for extra-terrestrial life. Here, we discuss the extreme physical properties possible for the first characterised rocky super-Earth, CoRoT-7b (R pl =1.58±0.10R Earth , M pl =6.9±1.2M Earth ). It is extremely close to its star (a=0.0171AU=4.48R st ), with its spin and orbital rotation likely...
In this study, the interaction of stellar wind plasma with the exosphere and possibly with the planetary magnetospheric environment of close-in rocky exoplanets is investigated. In particular, we focus on the “super-Earth” CoRoT-7b, which has been recently discovered by the CoRoT space observatory. The physical properties of such a planet, with an orbital distance of about 0.017AU from its host star,...
We revisit the idea of R. Bracewell and R. Angelet al.,that exoplanets around nearby stars could be detected in the IR (6–17 μm) and their spectra analyzed, searching for CO 2 , H 2 O, O 3 , CH 4 , and NH 3 spectral features. The presence, or absence, of CO 2 would be the indication of a deep similarity, or difference, with the atmospheres of telluric...
