Abundance ratios of volatile vs. refractory elements in planet-harbouring stars: hints of pollution?
A. Ecuvillon, G. Israelian, N. C. Santos +2
We present the [X/H] trends as function of the elemental condensation temperature Tc in 88 planet host stars and in a volume-limited comparison sample of 33 dwarfs without detected…
Abundances of refractory elements in the atmospheres of stars with extrasolar planets
G. Gilli, G. Israelian, A. Ecuvillon +2
This work presents a uniform and homogeneous study of chemical abundances of refractory elements in 101 stars with and 94 without known planetary companions. We carry out an in-dep…
Oxygen abundances in planet-harbouring stars. Comparison of different abundance indicators
A. Ecuvillon, G. Israelian, N. C. Santos +3
We present a detailed and uniform study of oxygen abundances in 155 solar type stars, 96 of which are planet hosts and 59 of which form part of a volume-limited comparison sample w…
Abundances of Na, Mg and Al in stars with giant planets
P. Beirao, N. C. Santos, G. Israelian +1
We present Na, Mg and Al abundances in a set of 98 stars with known giant planets, and in a comparison sample of 41 ``single'' stars. The results show that the [X/H] abundances (wi…
Spectroscopic metallicities for planet-host stars: extending the samples
N. C. Santos, G. Israelian, M. Mayor +4
We present stellar parameters and metallicities for 29 planet-host stars, as well as for a large volume-limited sample of 53 stars not known to be orbited by any planetary-mass com…
