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 CARMENES search for exoplanets around M dwarfs: Nine new double-line spectroscopic binary stars

D. Baroch, J. C. Morales, I. Ribas +27

Context. The CARMENES spectrograph is surveying ~300 M dwarf stars in search for exoplanets. Among the target stars, spectroscopic binary systems have been discovered, which can be…

The CARMENES search for exoplanets around M dwarfs. A Neptune-mass planet traversing the habitable zone around HD 180617

A. Kaminski, T. Trifonov, J. A. Caballero +37

Despite their activity, low-mass stars are of particular importance for the search of exoplanets by the means of Doppler spectroscopy, as planets with lower masses become detectabl…

The CARMENES search for exoplanets around M dwarfs: Radial-velocity variations of active stars in visual-channel spectra

L. Tal-Or, M. Zechmeister, A. Reiners +22

Previous simulations predicted the activity-induced radial-velocity (RV) variations of M dwarfs to range from cm/s to km/s, depending on various stellar and activit…

The CARMENES search for exoplanets around M dwarfs: Wing asymmetries of H, Na I D, and He I lines

B. Fuhrmeister, S. Czesla, J. H. M. M. Schmitt +13

Stellar activity is ubiquitously encountered in M dwarfs and often characterised by the H line. In the most active M dwarfs, H is found in emission, sometimes with a complex…
