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 SRG/eROSITA All-Sky Survey DR2: Cumulative X-ray catalogues from the first three surveys and multi-wavelength counterparts in the western Galactic hemisphere
M. E. Ramos-Ceja, G. Lamer, M. Salvato +111
The paper presents the second data release of the SRG/eROSITA all‑sky survey, providing catalogues of nearly two million X‑ray sources (point‑like and extended) from the first thre…
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…
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…
Searching the non-accreting white dwarf population in eROSITA data
S. Friedrich, C. Maitra, K. Dennerl +3
eROSITA is the soft X-ray instrument aboard the Spectrum Roentgen Gamma (SRG) satellite that is most sensitive in the energy range between 0.2 and 2.3 keV. Between December 2019 an…
