Beryllium anomalies in solar-type field stars
N. C. Santos, G. Israelian, S. Randich +2
We present a study of beryllium (Be) abundances in a large sample of field solar-type dwarfs and sub-giants spanning a large range of effective temperatures. The analysis shows tha…
Are beryllium abundances anomalous in stars with giant planets?
N. C. Santos, G. Israelian, R. J Garcia Lopez +5
In this paper we present beryllium (Be) abundances in a large sample of 41 extra-solar planet host stars, and for 29 stars without any known planetary-mass companion, spanning a la…
C, S, Zn and Cu abundances in planet-harbouring stars
A. Ecuvillon, G. Israelian, N. C. Santos +3
We present a detailed and uniform study of C, S, Zn and Cu abundances in a large set of planet host stars, as well as in a homogeneous comparison sample of solar-type dwarfs with n…
Cu and Zn in the early Galaxy
G. Bihain, G. Israelian, R. Rebolo +2
We present Cu and Zn abundances for 38 FGK stars, mostly dwarfs, spanning a metallicity range between solar and [Fe/H] =-3. The abundances were obtained using Kurucz's local therma…
Chemical Abundances in the Secondary Star in the Black Hole Binary A0620-00
Jonay I. Gonzalez-Hernandez, R. Rebolo, G. Israelian +3
Using a high resolution spectrum of the secondary star in the black hole binary A0620-00, we have derived the stellar parameters and veiling caused by the accretion disk in a consi…
Oxygen and Magnesium Abundance in the Ultra-Metal-Poor Giants CS22949-037 and CS29498-043: Challenges in Models of Atmospheres
G. Israelian, N. Shchukina, R. Rebolo +3
We report the results of a non-LTE Fe, O and Mg abundance analysis of the carbon-nitrogen-rich ultra-metal-poor giants CS29498--043 and CS22949--037. The abundance of oxygen has be…
