From Starspots to Stellar Coronal Mass Ejections—Revisiting Empirical Stellar Relations [PDF]

open access: yesAstrophysical Journal, 2021
Abstract Upcoming missions, including the James Webb Space Telescope, will soon characterize the atmospheres of terrestrial-type exoplanets in habitable zones around cool K- and M-type stars by searching for atmospheric biosignatures.

Indications of stellar coronal mass ejections through coronal dimmings [PDF]

open access: yesNature Astronomy, 2021
Coronal mass ejections (CMEs) are huge expulsions of magnetized matter from the Sun and stars, traversing space with speeds of millions of kilometers per hour. Solar CMEs can cause severe space weather disturbances and consumer power outages on Earth, whereas stellar CMEs may even pose a hazard to the habitability of exoplanets.

The Search for Stellar Coronal Mass Ejections

2017
Coronal mass ejections (CMEs) may dramatically impact habitability and atmospheric composition of planets around magnetically active stars, including young solar analogs and many M dwarfs. Theoretical predictions of such effects are limited by the lack of observations of stellar CMEs. This thesis addresses this gap through a search for the spectral and
