Young planets under extreme UV irradiation. I. Upper atmosphere modelling of the young exoplanet K2-33b
D. Kubyshkina, M. Lendl, L. Fossati +4
The K2-33 planetary system hosts one transiting ~5 R_E planet orbiting the young M-type host star. The planet's mass is still unknown, with an estimated upper limit of 5.4 M_J. The…
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…
Aerosol Constraints on the Atmosphere of the Hot Saturn-mass planet WASP-49b
Patricio Cubillos, Luca Fossati, Nikolai Erkaev +6
The strong, nearly wavelength-independent absorption cross section of aerosols produces featureless exoplanet transmission spectra, limiting our ability to characterize their atmos…
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…
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…
