X-ray detections of known exoplanet host stars in the sky. Known planet host stars are depicted as small grey dots. The Kepler field at RA = 300 deg as well as the increased density of known planets along the ecliptic due to the coverage by the K2 mission are visible. Detections in the German eROSITA sky with the eRASSl or eRASS2 survey are shown as filled red circles, previous detections with ROSAT, XMM-Newton, and Chandra are shown as filled black diamonds, open circles, and open squares, respectively.
