Discovery and origin of the radio emission from the multiple stellar system KQVel
P. Leto, L. M. Oskinova, C. S. Buemi +20
KQVel is a binary system composed of a slowly rotating magnetic Ap star with a companion of unknown nature. In this paper, we report the detection of its radio emission. We conduct…
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…
Coronal and chromospheric emission in A-type stars
Hans Moritz Günther, Carl Melis, J. Robrade +3
Cool stars on the main sequence generate X-rays from coronal activity, powered by a convective dynamo. With increasing temperature, the convective envelope becomes smaller and X-ra…
The high energy spectrum of Proxima Centauri simultaneously observed at X-ray and FUV wavelengths
B. Fuhrmeister, A. Zisik, P. C. Schneider +6
The M dwarf Proxima~Centauri is known to be magnetically active and it hosts a likely Earth-like planet in its habitable zone. Understanding the characteristics of stellar radiatio…
The eROSITA extragalactic CalPV serendipitous catalog
Teng Liu, Andrea Merloni, Julien Wolf +21
The eROSITA X-ray telescope on board the Spectrum-Roentgen-Gamma (SRG) observatory performed calibration and performance verification (CalPV) observations between September 2019 an…
