The CARMENES search for exoplanets around M dwarfs: Not-so-fine hyperfine-split vanadium lines in cool star spectra

Yutong Shan, Ansgar Reiners, Damian Fabbian +24

(Abridged) We characterize a series of neutral vanadium atomic absorption lines in the 800--910nm wavelength region of high signal-to-noise, high-resolution, telluric-corrected M-d…

The CARMENES search for exoplanets around M dwarfs -- Planet occurrence rates from a subsample of 71 stars

S. Sabotta, M. Schlecker, P. Chaturvedi +25

The CARMENES exoplanet survey of M dwarfs has obtained more than 18 000 spectra of 329 nearby M dwarfs over the past five years as part of its guaranteed time observations (GTO) pr…

The CARMENES search for exoplanets around M dwarfs, No evidence for a super-Earth in a 2-day orbit around GJ 1151

M. Perger, I. Ribas, G. Anglada-Escudé +20

The interaction between Earth-like exoplanets and the magnetic field of low-mass host stars are considered to produce weak emission signals at radio frequencies. A study using LOFA…

Detection of the hydrogen Balmer lines in the ultra-hot Jupiter WASP-33b

F. Yan, A. Wyttenbach, N. Casasayas-Barris +24

Ultra-hot Jupiters (UHJs) are highly irradiated giant exoplanets with extremely high day-side temperatures, which lead to thermal dissociation of most of the molecular species. It…

The CARMENES search for exoplanets around M dwarfs. Variability of the He I line at 10830 Å

B. Fuhrmeister, S. Czesla, L. Hildebrandt +23

The He I infrared (IR) triplet at 10830 Åis known as an activity indicator in solar-type stars and has become a primary diagnostic in exoplanetary transmission spectroscopy. He I l…

The CARMENES search for exoplanets around M dwarfs. Radial velocities and activity indicators from cross-correlation functions with weighted binary masks

M. Lafarga, I. Ribas, C. Lovis +24

For years, the standard procedure to measure radial velocities (RVs) of spectral observations consisted in cross-correlating the spectra with a binary mask, that is, a simple stell…
