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) …

We determined effective temperatures, surface gravities, and metallicities for a sample of
343 M dwarfs observed with CARMENES, the double-channel, high-resolution spectrograph …

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 …

Context. The Gl 486 system consists of a very nearby, relatively bright, weakly active M3. 5 V
star at just 8 pc with a warm transiting rocky planet of about 1.3 R⊕ and 3.0 M⊕. It is ideal …

Light from celestial objects interacts with the molecules of the Earth's atmosphere, resulting
in the production of telluric absorption lines in ground-based spectral data. Correcting for …

The detection of habitable worlds is one of humanity's greatest endeavors. Thus far,
astrobiological studies have shown that one of the most critical components for allowing life …

We present the first elemental abundance measurements of the K dwarf (K7V) exoplanet-
host star WASP-107 using high-resolution (R≃ 45,000), near-infrared (H-and K-band) …

Detailed chemical analyses of M dwarfs are scarce but necessary to constrain the formation
environment and internal structure of planets being found around them. We present …

We present an in-depth, high-resolution spectroscopic analysis of the M dwarf K2-18, which
hosts a sub-Neptune exoplanet in its habitable zone. We show our technique to accurately …

We present the abundances of magnesium (Mg) and silicon (Si) for 314 dwarf stars with
spectral types in the interval K7. 0–M5. 5 (T eff range≈ 4200–3050 K) observed with the …
