Lyα Absorption at Transits of HD 209458b: A Comparative Study of Various Mechanisms Under Different Conditions
M. L. Khodachenko, I. F. Shaikhislamov, H. Lammer +7
To shed more light on the nature of the observed Lyα absorption during transits of HD 209458b and to quantify the major mechanisms responsible for the production of fast hydrogen a…
Magma oceans and enhanced volcanism on TRAPPIST-1 planets due to induction heating
K. G. Kislyakova, L. Noack, C. P. Johnstone +6
Low-mass M stars are plentiful in the Universe and often host small, rocky planets detectable with the current instrumentation. Recently, seven small planets have been discovered o…
Effect of stellar wind induced magnetic fields on planetary obstacles of non-magnetized hot Jupiters
N. V. Erkaev, P. Odert, H. Lammer +7
We investigate the interaction between the magnetized stellar wind plasma and the partially ionized hydrodynamic hydrogen outflow from the escaping upper atmosphere of non- or weak…
How Expanded Ionospheres of Hot Jupiters Can Prevent Escape of Radio Emission Generated by the Cyclotron Maser Instability
Christof Weber, Helmut Lammer, Ildar Shaikhislamov +8
We present a study of plasma conditions in the atmospheres of the Hot Jupiters HD 209458b and HD 189733b and for an HD 209458b-like planet at orbit locations between 0.2-1 AU aroun…
Escape and fractionation of volatiles and noble gases from Mars-sized planetary embryos and growing protoplanets
P. Odert, H. Lammer, N. V. Erkaev +6
Planetary embryos form protoplanets via mutual collisions, which can lead to the development of magma oceans. During their solidification, large amounts of the mantles' volatile co…
Two regimes of interaction of a Hot Jupiter's escaping atmosphere with the stellar wind and generation of energized atomic hydrogen corona
I. F. Shaikhislamov, M. L. Khodachenko, H. Lammer +7
The interaction of escaping upper atmosphere of a hydrogen rich non-magnetized analog of HD209458b with a stellar wind of its host G-type star at different orbital distances is sim…
