3D Gas Dynamic Simulation of the Interaction Between the Exoplanet WASP-12b and Its Host Star

D. Bisikalo, P. Kaygorodov, D. Ionov +3

HST transit observations in the near-UV performed in 2009 made WASP-12b one of the most "mysterious" exoplanets; the system presents an early-ingress, which can be explained by the…

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"…

Probing the Blow-Off Criteria of Hydrogen-Rich "Super-Earths"

H. Lammer, N. V. Erkaev, P. Odert +3

The discovery of transiting "super-Earths" with inflated radii and known masses such as Kepler-11b-f, GJ 1214b and 55 Cnc e, indicates that these exoplanets did not lose their nebu…

Transiting exoplanets from the CoRoT space mission XXI. CoRoT-19b: A low density planet orbiting an old inactive F9V-star

E. W. Guenther, R. F. Diaz, J. -C. Gazzano +51

Observations of transiting extrasolar planets are of key importance to our understanding of planets because their mass, radius, and mass density can be determined. The CoRoT space…
