The field of exoplanet atmospheric characterization has recently made considerable
advances with the advent of high-resolution spectroscopy from large ground-based …

Context. The CARMENES instrument, installed at the 3.5 m telescope of the Calar Alto
Observatory in Almería, Spain, was conceived to deliver high-accuracy radial velocity (RV) …

Context. Ultra-hot Jupiters are excellent laboratories for the study of exoplanetary
atmospheres. WASP-121b is one of the most studied; many recent analyses of its …

The chemical compositions of stars encode the history of the universe and are thus
fundamental for advancing our knowledge of astrophysics and cosmology. However …

Aims. We report on ESPRESSO high-resolution transmission spectroscopic observations of
two primary transits of the highly irradiated, ultra-hot Jupiter-sized planet, WASP-76b. We …

We analyze two high-resolution spectral transit time series of the hot Jupiter HAT-P-32 b
obtained with the CARMENES spectrograph. Our new XMM-Newton X-ray observations of …

High resolution transit spectroscopy has proven to be a reliable technique for the
characterization of the chemical composition of exoplanet atmospheres. Taking advantage …

Ultra-hot Jupiters are highly irradiated gas giants with equilibrium temperatures typically
higher than 2000 K. Atmospheric studies of these planets have shown that their transmission …

Context. The population of close-in exoplanets features a desert of hot Neptunes whose
origin remains uncertain. These planets may have lost their atmosphere, eroding into mini …

The CARMENES instrument consists of two cross-dispersed´ echelle spectrographs, which
together cover the wavelength range from 5,200 to 17,100˚ A. During its first five years of …
