Hunting for Stellar Coronal Mass Ejections
Heidi Korhonen, Krisztian Vida, Martin Leitzinger +2
Coronal mass ejections (CMEs) are explosive events that occur basically daily on the Sun. It is thought that these events play a crucial role in the angular momentum and mass loss…
An Overabundance of Low-density Neptune-like Planets
Patricio Cubillos, Nikolai V. Erkaev, Ines Juvan +6
We present a uniform analysis of the atmospheric escape rate of Neptune-like planets with estimated radius and mass (restricted to ). For each planet we c…
Indications of stellar prominence oscillations on fast rotating stars: the cases of HK Aqr and PZ Tel
M. Leitzinger, P. Odert, T. V. Zaqarashvili +3
We present the analysis of six nights of spectroscopic monitoring of two young and fast rotating late-type stars, namely the dMe star HK Aqr and the dG/dK star PZ Tel. On both star…
Identifying the "true" radius of the hot sub-Neptune CoRoT-24b by mass loss modelling
H. Lammer, N. V. Erkaev, L. Fossati +8
For the hot exoplanets CoRoT-24b and CoRoT-24c, observations have provided transit radii R of 3.70.4 R and 4.90.5 R, and masses of 5.…
Investigating magnetic activity in very stable stellar magnetic fields: long-term photometric and spectroscopic study of the fully convective M4 dwarf V374 Peg
K. Vida, L. Kriskovics, K. Oláh +8
The ultrafast-rotating () fully convective single M4 dwarf V374 Peg is a well-known laboratory for studying intense stellar activity in a stable magnet…
Thermal mass loss of protoplanetary cores with hydrogen-dominated atmospheres: The influences of ionization and orbital distance
N. V. Erkaev, H. Lammer, P. Odert +4
We investigate the loss rates of the hydrogen atmospheres of terrestrial planets with a range of masses and orbital distances by assuming a stellar extreme ultraviolet (EUV) lumino…
