The X-ray catalogue of FGK stars within 10 pc: The coronal temperature-brightness relation explained with the RTV scaling law
M. M. Bennedik, B. Stelzer, M. Caramazza +3
A comprehensive measurement of stellar X-ray emission has important implications for our understanding of stellar dynamos, exoplanet atmosphere loss, and evaporation of protoplanet…
Quiet, but not silent. The X-ray activity of the Maunder minimum star HD 166620
M. M. Bennedik, B. Stelzer, H. Isaacson +3
As the only known unambiguous star in a Maunder minimum-like chromospheric activity state, the properties of HD 166620 can provide valuable insight into the behaviour of the Sun du…
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…
The Gaia-ESO Survey: Target selection of open cluster stars
A. Bragaglia, E. Alfaro, E. Flaccomio +36
The Gaia-ESO Survey (GES) is a public, high-resolution spectroscopic survey with FLAMES@VLT. GES targeted in particular a large sample of open clusters (OCs) of all ages. The diffe…
Supersaturation and activity-rotation relation in PMS stars: the young Cluster h Per
C. Argiroffi, M. Caramazza, G. Micela +4
The magnetic activity of late-type MS stars is characterized by different regimes, and their activity levels are well described by Ro, the ratio between P_rot and the convective tu…
