Determination of spectroscopic parameters for 313 M dwarf stars from their APOGEE Data Release 16 H-band spectra
Pedro Sarmento, Bárbara Rojas-Ayala, Elisa Delgado Mena +1
The scientific community's interest on the stellar parameters of M dwarfs has been increasing over the last few years, with potential applications ranging from galactic characteriz…
The Gaia-ESO Survey: Calibrating the lithium-age relation with open clusters and associations. I. Cluster age range and initial membership selections
M. L. Gutiérrez Albarrán, D. Montes, M. Gómez Garrido +33
Previous studies of open clusters have shown that lithium depletion is not only strongly age dependent but also shows a complex pattern with other parameters that is not yet unders…
Benchmark stars, benchmark spectrographs: Detailed spectroscopic comparison of ESPRESSO, PEPSI, and HARPS data for Gaia benchmark stars
V. Adibekyan, S. G. Sousa, N. C. Santos +14
Gaia benchmark stars are selected to be calibration stars for different spectroscopic surveys. Very high-quality and homogeneous spectroscopic data for these stars are therefore re…
Chemical abundances of 1111 FGK stars from the HARPS-GTO planet search sample. III. Sulfur
Ana Rita Costa Silva, Elisa Delgado Mena, Maria Tsantaki
Context. Elemental abundances are of prime importance to help us reconstruct the origin and evolution of stars and galaxies in our Universe. Sulfur abundances have not been as heav…
The Gaia-ESO Survey: Carbon abundance in the Galactic thin and thick disks
Mariagrazia Franchini, Carlo Morossi, Paolo Di Marcantonio +24
This paper focuses on carbon that is one of the most abundant elements in the Universe and is of high importance in the field of nucleosynthesis and galactic and stellar evolution.…
Abundance to age ratios in the HARPS-GTO sample with Gaia DR2: Chemical clocks for a range of [Fe/H]
E. Delgado Mena, A. Moya, V. Adibekyan +8
[ABRIDGED] The purpose of this work is to evaluate how several elements produced by different nucleosynthesis processes behave with stellar age and provide empirical relations to d…
