Chemical abundances of main-sequence, turnoff, subgiant, and red giant stars from APOGEE Spectra. I. Signatures of diffusion in the open cluster M67
(IOP Publishing Ltd, 2018)
Detailed chemical abundance distributions for 14 elements are derived for eight high-probability stellar members of the solar metallicity old open cluster M67 with an age of similar to 4 Gyr. The eight stars consist of ...
The metal-poor dwarf irregular galaxy candidate next to Mrk 1172

Propiedades físicas de estrellas con exoplanetas y anillos circunestelares /
(2008-03)
Estudiamos diferentes aspectos de estrellas con exoplanetas (EH) y de estrellas de tipo Vega. Detectamos excesos IR en 20% de las estrellas EH, el cual se atribuye a la presencia de polvo circunestelar.

Correlations between mass, stellar kinematics, and gas metallicity in eagle galaxies
(Oxford University Press, 2020-05)
The metallicity of star-forming gas in galaxies from the eagle (Evolution and Assembly of GaLaxies and their Environments) simulations increases with stellar mass. Here, we investigate whether the scatter around this ...

Chemical abundances and kinematics of 257 G-, K-type field giants. Setting a base for further analysis of giant-planet properties orbiting evolved stars
(OXFORD UNIV PRESS, 2015)
We performed a uniform and detailed abundance analysis of 12 refractory elements (Na, Mg, Al, Si, Ca, Ti, Cr, Ni, Co, Sc, Mn, and V) for a sample of 257 G-and K-type evolved stars from the CORALIE planet search programme. ...
The oxygen abundance gradients in the gas discs of galaxies in the EAGLE simulation
(2019)
We use the EAGLE simulations to study the oxygen abundance gradients of gas discs in galaxies within the stellar mass range [10(9.5), 10(10.8)] similar to M-circle dot at z = 0. The estimated median oxygen gradient is ...
A FIRST CONSTRAINT ON THE THICK DISK SCALE LENGTH: DIFFERENTIAL RADIAL ABUNDANCES IN K GIANTS AT GALACTOCENTRIC RADII 4, 8, AND 12 kpc
(IOP PUBLISHING LTD, 2011)
Based on high-resolution spectra obtained with the MIKE spectrograph on the Magellan telescopes, we present detailed elemental abundances for 20 red giant stars in the outer Galactic disk, located at Galactocentric distances ...
