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…
Galactic Evolution of Nitrogen
G. Israelian, A. Ecuvillon, R. Rebolo +3
We present detailed spectroscopic analysis of nitrogen abundances in 31 unevolved metal-poor stars analysed by spectral synthesis of the near-UV NH band at 3360 A observed at high…
Nitrogen abundances in Planet-harbouring stars
A. Ecuvillon, G. Israelian, N. C. Santos +3
We present a detailed spectroscopic analysis of nitrogen abundances in 91 solar-type stars, 66 with and 25 without known planetary mass companions. All comparison sample stars and…
