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…
NIRwave: A wave-turbulence-driven solar wind model constrained by PSP observations
Simon Schleich, Sudeshna Boro Saikia, Udo Ziegler +2
We generate a model description of the solar wind based on an explicit wave-turbulence-driven heating mechanism, and constrain our model with observational data. We included an exp…
Absolute Ca II H & K and H-alpha flux measurements of low-mass stars: Extending to M dwarfs
C. J. Marvin, A. Reiners, G. Anglada-Escudé +2
Context: With the recent surge of planetary surveys focusing on detecting Earth-mass planets around M dwarfs, it is becoming more important to understand chromospheric activity in…
The connection between stellar activity cycles and magnetic field topology
V. See, M. Jardine, A. A. Vidotto +14
Zeeman Doppler imaging has successfully mapped the large-scale magnetic fields of stars over a large range of spectral types, rotation periods and ages. When observed over multiple…
Magnetic fields on young, moderately rotating Sun-like stars - I: HD~35296 and HD~29615
Ian Waite, Stephen Marsden, Bradley Carter +4
Observations of the magnetic fields of young solar-type stars provide a way to investigate the signatures of their magnetic activity and dynamos. Spectropolarimetry enables the stu…
