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 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…
Ground-based detection of an extended helium atmosphere in the Saturn-mass exoplanet WASP-69b
Lisa Nortmann, Enric Pallé, Michael Salz +25
Hot gas giant exoplanets can lose part of their atmosphere due to strong stellar irradiation, affecting their physical and chemical evolution. Studies of atmospheric escape from ex…
The XUV environments of exoplanets from Jupiter-size to super-Earth
George W. King, Peter J. Wheatley, Michael Salz +8
Planets that reside close-in to their host star are subject to intense high-energy irradiation. Extreme-ultraviolet (EUV) and X-ray radiation (together, XUV) is thought to drive ma…
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…
Coronal X-ray emission and planetary irradiation in HD 209458
S. Czesla, M. Salz, P. C. Schneider +2
HD 209458 is one of the benchmark objects in the study of hot Jupiter atmospheres and their evaporation through planetary winds. The expansion of the planetary atmosphere is though…
