The Volans-Carina association An X-ray Bridge Between Younger and Older Stellar Populations
Daniela Muñoz-Giraldo, Beate Stelzer, Alex Binks +3
Nearby young moving groups (NYMGs) provide benchmarks for studying the evolution of magnetic activity and planetary environments at early ages. The Volans-Carina association (VCA),…
Long-term stellar activity of M dwarfs: A combined K2 and TESS study of two early M-type stars
St. Raetz, B. Stelzer
Studies of the rotation and activity of M type stars are essential to enhance our understanding of stellar dynamos and angular momentum evolution. Using the outstanding photometric…
Transitions in magnetic behavior at the substellar boundary
E. Magaudda, B. Stelzer, R. A. Osten +3
We aim at advancing our understanding of magnetic activity and the underlying dynamo mechanism at the end of the main-sequence. To this end, we collected simultaneous X-ray and rad…
Complete X-ray census of Mdwarfs in the solar Neighborhood I. GJ 745 AB: Coronal-hole Stars in the 10 pc Sample
M. Caramazza, B. Stelzer, E. Magaudda +4
We have embarked in a systematic study of the X-ray emission in a volume-limited sample of M dwarf stars, in order to explore the full range of activity levels present in their cor…
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…
