González Hernández, J. I. ; Montes Gutiérrez, David ; Tabernero Guzmán, Hugo Martín ; otros, ... | EDP Sciencies | 2015-10Context. In the current era of large spectroscopic surveys of the Milky Way, reference stars for calibrating astrophysical parameters and chemical abundances are of paramount importance. Aims. We determine elemental abundances of Mg, Si, Ca, Sc,[...]texto impreso
Tabernero Guzmán, Hugo Martín ; Marfil, E. ; Montes Gutiérrez, David ; González Hernández, J.I. | EDP SCIENCES S A | 2019-08-20Context. StePar is an automatic code written in Python 3.X designed to compute the stellar atmospheric parameters T_(eff), log g, [Fe/H], and ? of FGK-type stars by means of the equivalent width (EW) method. This code has already been extensivel[...]texto impreso
González Hernández, J. I. ; Montes Gutiérrez, David ; Tabernero Guzmán, Hugo Martín | EDP Sciencies | 2015-05Context. Stars are born together from giant molecular clouds and, if we assume that the priors were chemically homogeneous and well-mixed, we expect them to share the same chemical composition. Most of the stellar aggregates are disrupted while [...]texto impreso
Cortés Contreras, Miriam ; Tabernero Guzmán, Hugo Martín ; Montes Gutiérrez, David ; Gómez Marfil, Emilio ; López Gallifa, Álvaro | EDP Sciencies | 2020-10-23Due to their ubiquity and very long main-sequence lifetimes, abundance determinations in M dwarfs provide a powerful and alternative tool to GK dwarfs to study the formation and chemical enrichment history of our Galaxy. In this study, abundance[...]texto impreso
Gutiérrez Albarrán, M.L. ; Montes Gutiérrez, David ; Gómez Garrido, Miguel ; Tabernero Guzmán, Hugo Martín ; Gómez Marfil, Emilio | EDP Sciencies | 2020-11-05Context. 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 understood. For pre- and main-sequence late-type stars, these [...]
