The Great Flare of 2021 November 19 on AD Leo. Simultaneous XMM-Newton and TESS observations
B. Stelzer, M. Caramazza, St. Raetz +2
We present a detailed analysis of a superflare on the active M dwarf star AD Leonis. The event presents a rare case of a stellar flare observed simultaneously in X-rays (with XMM-N…
Flares and rotation of M dwarfs with habitable zones accessible to TESS planet detections
B. Stelzer, M. Bogner, E. Magaudda +1
We characterize the magnetic activity of M dwarfs to provide the planet community with information on the energy input from the star; in particular, in addition to the frequency of…
YETI follow-up observations of the T Tauri star CVSO30 with transit-like dips
R. Bischoff, St. Raetz, M. Fernández +13
The T Tauri star CVSO30, also known as PTFO8-8695, was studied intensively with ground based telescopes as well as with satellites over the last decade. It showed a variable light…
First eROSITA-TESS results for M dwarfs: Mass dependence of the X-ray activity rotation relation and an assessment of sensitivity limits
E. Magaudda, B. Stelzer, St. Raetz
We present a study of the activity-rotation relation for M dwarf stars, using new X-ray data from the ROentgen Survey with an Imaging Telescope Array (eROSITA) on board the Russian…
