The stellar content of the ROSAT all-sky survey
S. Freund, S. Czesla, J. Robrade +2
We present and apply a method to identify the stellar content of the ROSAT all-sky survey (RASS). We performed a crossmatch between the RASS sources and stellar candidates selected…
X-raying the Sco-Cen OB association: The low-mass stellar population revealed by eROSITA
J. H. M. M. Schmitt, S. Czesla, S. Freund +2
We present the results of the first X-ray all-sky survey (eRASS1) performed by the eROSITA instrument on board the Spectrum-Roentgen-Gamma (SRG) observatory of the Sco-Cen OB assoc…
The eROSITA Final Equatorial-Depth Survey (eFEDS). The stellar counterparts of eROSITA sources identified by machine learning and Bayesian algorithms
P. C. Schneider, S. Freund, S. Czesla +3
Stars are ubiquitous X-ray emitters and will be a substantial fraction of the X-ray sources detected in the on-going all-sky survey performed by the eROSITA instrument aboard the S…
The X-ray view of the Hyades cluster: updated
S. Freund, J. Robrade, P. C. Schneider +1
We revisit the X-ray properties of the main-sequence Hyades members and the relation between X-ray emission and stellar rotation. As input catalog for Hyades members, we combined t…
The stellar content of the XMM-Newton slew survey
S. Freund, J. Robrade, C. Schneider +1
We present a detailed analysis of the stellar content of the current version of the XMM-Newton slew survey (XMMSL2). Since stars emit only a small fraction of their total luminosit…
