Galactic cosmic rays on extrasolar Earth-like planets: II. Atmospheric implications
J. --M. Grießmeier, F. Tabataba-Vakili, A. Stadelmann +2
(abridged abstract) Theoretical arguments indicate that close-in terrestial exoplanets may have weak magnetic fields. As described in the companion article (Paper I), a weak magnet…
Galactic cosmic rays on extrasolar Earth-like planets I. Cosmic ray flux
J. -M. Grießmeier, F. Tabataba-Vakili, A. Stadelmann +2
(abridged abstract) Theoretical arguments indicate that close-in terrestial exoplanets may have weak magnetic fields, especially in the case of planets more massive than Earth (sup…
Stellar activity and magnetic shielding
J. -M. Grießmeier, M. Khodachenko, H. Lammer +3
Stellar activity has a particularly strong influence on planets at small orbital distances, such as close-in exoplanets. For such planets, we present two extreme cases of stellar v…
On the protection of extrasolar Earth-like planets around K/M stars against galactic cosmic rays
J. -M. Grießmeier, A. Stadelmann, J. L. Grenfell +2
Previous studies have shown that extrasolar Earth-like planets in close-in habitable zones around M-stars are weakly protected against galactic cosmic rays (GCRs), leading to a str…
