Extreme hydrodynamic atmospheric loss near the critical thermal escape regime
N. V. Erkaev, H. Lammer, P. Odert +2
By considering martian-like planetary embryos inside the habitable zone of solar-like stars we study the behavior of the hydrodynamic atmospheric escape of hydrogen for small value…
XUV exposed non-hydrostatic hydrogen-rich upper atmospheres of terrestrial planets. Part I: Atmospheric expansion and thermal escape
N. V. Erkaev, H. Lammer, P. Odert +6
The recently discovered low-density "super-Earths" Kepler-11b, Kepler-11f, Kepler-11d, Kepler-11e, and planets such as GJ 1214b represent most likely planets which are surrounded b…
XUV exposed, non-hydrostatic hydrogen-rich upper atmospheres of terrestrial planets II: Hydrogen coronae and ion escape
K. G. Kislyakova, H. Lammer, M. Holmström +8
We study the interactions between the stellar wind plasma flow of a typical M star, such as GJ 436, and hydrogen-rich upper atmospheres of an Earth-like planet and a "super-Earth"…
Properties of the short period CoRoT-planet population II: The impact of loss processes on planet masses from Neptunes to Jupiters
Helmut Lammer, T. Penz, G. Wuchterl +4
The orbital distance at which close-in exoplanets maintain their initial mass is investigated by modelling the maximum expected thermal and nonthermal mass loss rates over several…
