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
The authors compile an X‑ray catalog of FGK main‑sequence stars within 10 pc, derive coronal temperatures and X‑ray fluxes from eROSITA, XMM‑Newton and ROSAT data, and show that th…

The Volans-Carina association An X-ray Bridge Between Younger and Older Stellar Populations
Daniela Muñoz-Giraldo, Beate Stelzer, Alex Binks +3
The paper refines the membership of the Volans‑Carina association using Gaia DR3 data and provides a nearly complete X‑ray census, showing its stars have coronal activity comparabl…

The Age and High Energy Environment of the Very Young Transiting Exoplanet TOI 1227b
Attila Varga, Joel H. Kastner, Alexander S. Binks +2
The mid-M star TOI~1227 hosts among the youngest known transiting exoplanets. We have conducted new X-ray imaging and optical spectroscopic observations of TOI 1227 aimed at ascert…
