We provide a new collection of spectra of 35 carbon stars obtained with the ESO/VLT X-Shooter instrument as part of the X-Shooter Spectral Library project. The...
Carbon, nitrogen, and oxygen abundance gradients in M101 and M31
We present deep spectrophotometry of 18 H II regions in the nearby massive spiral galaxies M 101 and M 31. We have obtained direct determinations of electron...
Carbon, Nitrogen, and Oxygen Galactic Gradients: A Solution to the Carbon Enrichment Problem
Eleven models of Galactic chemical evolution, differing in the carbon, nitrogen, and oxygen yields adopted, have been computed to reproduce the Galactic O/H...
Carbon-enhanced metal-poor stars enriched in s-process and r-process elements
We present an on-going project consisting of analysis of a sample of twenty-five metal-poor stars, most of them carbon-enriched and thus tagged carbon-enhanced...
CaRM: Exploring the chromatic Rossiter-McLaughlin effect. The cases of HD 189733b and WASP-127b
Aims: In this paper we introduce CaRM, a semi-automatic code for the retrieval of broadband transmission spectra of transiting planets through the chromatic...
CARMENES detection of the Ca II infrared triplet and possible evidence of He I in the atmosphere of WASP-76b
Ultra-hot Jupiters are highly irradiated gas giants with equilibrium temperatures typically higher than 2000 K. Atmospheric studies of these planets have shown...
CARMENES input catalog of M dwarfs. VII. New rotation periods for the survey stars and their correlations with stellar activity
Aims: Knowledge of rotation periods (P rot) is important for understanding the magnetic activity and angular momentum evolution of late-type stars, as well as...
CARMENES input catalogue of M dwarfs. II. High-resolution imaging with FastCam
Aims: We search for low-mass companions of M dwarfs and characterize their multiplicity fraction with the purpose of helping in the selection of the most...
CARMENES input catalogue of M dwarfs. IV. New rotation periods from photometric time series
Aims: The main goal of this work is to measure rotation periods of the M-type dwarf stars being observed by the CARMENES exoplanet survey to help distinguish...
