The corona of GJ 1151 in the context of star-planet interaction
G. Foster, K. Poppenhaeger, J. D. Alvarado-Gómez +1
The low-mass star GJ 1151 has been reported to display variable low-frequency radio emission, which has been interpreted as a signpost of coronal star-planet interactions with an u…
White paper for Chandra cool attitude targets (CAT): Stellar activity with TESS and Chandra
Hans Moritz Günther, David A. Principe, Carl Melis +9
All cool stars show magnetic activity, and X-ray emission is the hallmark of this activity. Gaining an understanding of activity aids us in answering fundamental questions about st…
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…
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…
Spectral characterization and differential rotation study of active CoRoT stars
Evangelos Nagel, Stefan Czesla, Jürgen H. M. M. Schmitt
The CoRoT space telescope observed nearly 160 000 light curves. Among the most outstanding is that of the young, active planet host star CoRoT-2A. In addition to deep planetary tra…
