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…

astro-ph.HE2026

The average X-ray spectrum of the volume-complete M-, F-, G-, and K-type star sample within 10 pc of the Sun

Xueying Zheng, Gabriele Ponti, Nicola Locatelli +15

F, G, K and M type stars are the most abundant stellar population in the Milky Way and are expected to contribute to its diffuse X-ray emission. Yet their intrinsic average X-ray s…

Eating planets makes you younger: The magnetic dynamo rejuvenation of GJ 504 by planetary engulfment

S. Bellotti, C. Pezzotti, G. Buldgen +3

With the discovery of a few thousand exoplanets, questions have been raised regarding star-planet interactions and whether the presence of a companion may affect stellar properties…

Low-mass stars dominate the hot (0.7 keV) Galactic X-ray emission

G. Ponti, M. C. H. Yeung, G. Stel +12

The circumgalactic medium (CGM) of the Milky Way is composed of a tenuous atmosphere filled with multi-phase plasma, including a warm-hot virialised component. Recent studies sugge…

The X-ray luminosity function of stars observed with SRG/eROSITA

Nicola Locatelli, Gabriele Ponti, Enza Magaudda +1

Background diffuse X-ray emission is contributed in large part by the emission of point sources not individually resolved. While this is established since decades for the contribut…

Is planetary inward migration responsible for GJ 504's fast rotation and bright X-ray luminosity? New constraints from eROSITA

C. Pezzotti, G. Buldgen, E. Magaudda +4

The discovery of an increasing variety of exoplanets in very close orbits around their host stars raised many questions about how stars and planets interact, and to which extent ho…
