Montes Gutiérrez, David ; González Peinado, R. ; Tabernero, H. M. ; Caballero, J. A. ; Gómez Marfil, Emilio ; Alonso Floriano, F. J. ; Cortés Contreras, Miriam ; González Hernández, J. I. ; Klutsch, A. ; Moreno Jodar, C. | Oxford Univ Press | 2018-09We investigated almost 500 stars distributed among 193 binary or multiple systems made of late-E, G-, or earl y-K-primaries and late-K- or M-dwarf companion candidates, For all of them, we compiled or measured coordinates, J-band magnitudes, spe[...]texto impreso
Stellar kinematic groups are kinematical coherent groups of stars that might have a common origin. These groups are dispersed throughout the Galaxy over time by the tidal effects of both Galactic rotation and disc heating, although their chemica[...]texto impreso
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

I. ; Kaminski, A. ; Nagel, E. ; Jeffers, S.V. ; Reiners, A. ; Ribas, I. ; Quirrenbach, A. ; Amado, P.J. | Oxford University Press. | 2020-03With the purpose of assessing classic spectroscopic methods on high-resolution and high signal-to-noise ratio spectra in the near-infrared wavelength region, we selected a sample of 65 F-, G-, and K-type stars observed with CARMENES, the new, ul[...]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
Context. The Gaia-ESO Public Spectroscopic Survey is obtaining high-quality spectroscopic data for about 10^5 stars using FLAMES at the VLT. With the FLAMES-UVES link, high-resolution spectra are being collected for about 5 000 FGK-type stars. A[...]
