Scientific paper

We present new models for the atmospheres of extrasolar Super-Earths. Such planets are now being discovered, and it is expected that a substantially larger group will be uncovered in the coming years by the CoRoT and Kepler missions. It remains uncertain as to whether Super-Earths are able to retain massive hydrogen-rich atmospheres like Neptune, or if they experience significant escape of lightweight elements resulting in atmospheres
more like those of the terrestrial planets in our Solar System. We examine
some of the possible scenarios for Super-Earth atmospheres, and we determine methods for differentiating between these through observations of the planet's emission and transmission spectra.
