eROSITA all-sky survey - stars and optical loading

J. Robrade, K. Dennerl, M. J. Freyberg +1

eROSITA (extended ROentgen Survey with an Imaging Telescope Array) on board the Spectrum-Roentgen-Gamma (SRG) spacecraft has performed the eROSITA All-Sky Survey (eRASS) at X-ray e…

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…

A long-duration superflare on the K giant HD 251108

Hans Moritz Günther, Dheeraj Pasham, Alexander Binks +10

Many giant stars are magnetically active, which causes rotational variability, chromospheric emission lines, and X-ray emission. Large outbursts in these emission features can set…

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…

The SRG/eROSITA all-sky survey: First X-ray catalogues and data release of the western Galactic hemisphere

A. Merloni, G. Lamer, T. Liu +142

The eROSITA telescope array aboard the Spektrum Roentgen Gamma (SRG) satellite began surveying the sky in December 2019, with the aim of producing all-sky X-ray source lists and sk…

''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…
