Determining the mass loss limit for close-in exoplanets: what can we learn from transit observations?
Aims. We study the possible atmospheric mass loss from 57 known transiting exoplanets around F, G, K, and M-type stars over evolutionary timescales. For stellar wind induced mass loss studies, weExpand
Heating and evaporation of Icy particles in the vicinity of comets
Abstract Although the detailed structure of the surface layers of a cometary nucleus is still unknown, there are good reasons that favor a porous and fragile ice/dust mixture. Such a nucleus willExpand
Loss of water from Mars: Implications for the oxidation of the soil
Abstract The evolution of the martian atmosphere with regard to its H 2 O inventory is influenced by thermal loss processes of H, H 2 , nonthermal atmospheric loss processes of H + , H 2 + , O, O + ,Expand
Atmospheric and water loss from early Venus
Abstract Previous interpretations of the Pioneer Venus mass spectrometer data of the deuterium to hydrogen ( D / H ) ratio of 1.9 × 10 - 2 or 120 ± 40 times the terrestrial value indicate that VenusExpand
Coronal mass ejection (CME) activity of low mass M stars as an important factor for the habitability of terrestrial exoplanets. II. CME-induced ion pick up of Earth-like exoplanets in close-in
Atmospheric erosion of CO2-rich Earth-size exoplanets due to coronal mass ejection (CME)-induced ion pick up within close-in habitable zones of active M-type dwarf stars is investigated. Since MExpand
Processes that Promote and Deplete the Exosphere of Mercury
Abstract It has been speculated that the composition of the exosphere is related to the composition of Mercury’s crustal materials. If this relationship is true, then inferences regarding the bulkExpand
