X-ray counterparts to stellar MeerKAT Galactic-plane compact radio sources
O. D. Egbo, P. J. Groot, D. A. H. Buckley +5
Radio emission from magnetically active stars arises mainly from non-thermal processes and complements high-energy X-ray emission. Sensitive, wide-field radio and X-ray surveys now…
The stellar corona-chromosphere connection. A comprehensive study of X-ray and Ca II IRT fluxes from eROSITA and Gaia
S. Freund, S. Czesla, B. Fuhrmeister +4
Stellar activity can be observed at different wavelengths in a variety of different activity indicators. We investigated the correlation between coronal and chromospheric emissions…
Compact white-dwarf binaries in the combined SRG/eROSITA/SDSS eFEDS survey
A. Schwope, J. Kurpas, P. Baecke +22
Aims. Compact white-dwarf binaries are selected from spectra obtained in the early SDSS-V plate program. A dedicated set of SDSS plate observations were carried out in the eFEDS fi…
The SRG/eROSITA all-sky survey -- Identifying the coronal content with HamStar
S. Freund, S. Czesla, P. Predehl +6
The first eROSITA all-sky survey (eRASS1) performed on board the Spectrum-Roentgen-Gamma mission (SRG) provides more than 900,000 X-ray sources in the 0.2 - 2.3 keV band located in…
''Forbidden" stars in the eROSITA all-sky survey: X-ray emission from very late-type giants
J. H. M. M. Schmitt, M. Hünsch, P. C. Schneider +4
We present the results of the first X-ray all-sky survey (eRASS1) performed by the eROSITA instrument onboard the Spectrum-Roentgen-Gamma (SRG) mission on X-ray emitting red giants…
