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…
Stellar Coronal Mass Ejections I. Estimating occurrence frequencies and mass-loss rates
P. Odert, M. Leitzinger, A. Hanslmeier +1
Stellar coronal mass ejections (CMEs) may play an important role in mass- and angular momentum loss of young Sun-like stars. If occurring frequently, they may also have a strong ef…
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…
