X-ray detection of astrospheres around three main-sequence stars and their mass-loss rates
K. G. Kislyakova, M. Güdel, D. Koutroumpa +3
Stellar winds of cool main sequence stars are very difficult to constrain observationally. One way to measure stellar mass loss rates is to detect soft X-ray emission from stellar…
Airy worlds or barren rocks? On the survivability of secondary atmospheres around the TRAPPIST-1 planets
Gwenaël Van Looveren, Manuel Güdel, Sudeshna Boro Saikia +1
In this work we aim to determine the atmospheric survivability of the TRAPPIST-1 planets by modelling the response of the upper atmosphere to incoming stellar high-energy radiation…
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…
Magnetic moment and plasma environment of HD 209458b as determined from Ly observations
K. G. Kislyakova, M. Holmström, H. Lammer +2
Transit observations of HD 209458b in the stellar Lyman- (Ly) line revealed strong absorption in both blue and red wings of the line interpreted as hydrogen atoms escaping fr…
