| Zusammenfassung |
| The recently discovered super-Earth GJ 1214b is an interesting and unique object. Its
observed mass (6.55M-) and radius (~ 2.7R-) yield a rather low mean density of
1.87 g cm-3, so the planet is likely to possess a gaseous envelope. Since the object is
orbiting at a very close distance of 0.014 AU to its host star, the question arises how
atmospheric escape has influenced the evolution of this planet. We present the results of
energy-limited escape calculations, including Roche lobe effects, appropriate heating
efficiencies, and evolution of the host star’s XUV luminosity, to explore possible scenarios of
the evolution of this planet. |
