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…

Fundamental properties of pre-main sequence stars in young, southern star forming regions: metallicities

David J. James, Claudio Melo, Nuno C. Santos +1

Aims: The primary motivation for this project is to search for metal-rich star forming regions, in which, stars of super-solar metallicity will be created, as hopefully, will be ex…

ELODIE metallicity-biased search for transiting Hot Jupiters II. A very hot Jupiter transiting the bright K star HD189733

Francois Bouchy, Stephane Udry, Michel Mayor +9

Among the 160 known exoplanets, mainly detected in large radial-velocity surveys, only 8 have a characterization of their actual mass and radius thanks to the two complementary met…

Elodie metallicity-biased search for transiting Hot Jupiters I. Two Hot Jupiters orbiting the slightly evolved stars HD118203 and HD149143

R. Da Silva, S. Udry, F. Bouchy +7

We report the discovery of a new planet candidate orbiting the subgiant star HD118203 with a period of P=6.1335 days. The best Keplerian solution yields an eccentricity e=0.31 and…

Abundance ratios of volatile vs. refractory elements: hints of pollutions?

A. Ecuvillon, G. Israelian, N. C. Santos +2

We present the abundance ratios [X/H] of a large set of chemical species with condensation temperatures from 75 to 1600 K in an almost complete set of 105 planet-host stars and in…
