N in turn-off stars of NGC 6397 and NGC 6752
L. Pasquini, A. Ecuvillon, P. Bonifacio +1
We measure the nitrogen abundance in 5 Turn Off(TO) stars of the Globular Clusters NGC 6397 and NGC 6752, and compare the cluster abundances with those of field stars of comparable…
Refined parameters and spectroscopic transit of the super-massive planet HD147506b
B. Loeillet, A. Shporer, F. Bouchy +26
In this paper, we report a refined determination of the orbital parameters and the detection of the Rossiter-McLaughlin effect of the recently discovered transiting exoplanet HD147…
Kinematics of planet-host stars and their relation with dynamical streams in the solar neighbourhood
A. Ecuvillon, G. Israelian, F. Pont +2
We present a detailed study on the kinematics of metal-rich stars with and without planets, and their relation with the Hyades, Sirius and Hercules dynamical streams in the solar n…
Chemical abundances for the transiting planet host stars OGLE-TR-10, 56, 111, 113, 132 and TrES-1. Abundances in different galactic populations
N. C. Santos, A. Ecuvillon, G. Israelian +6
We used the UVES spectrograph (VLT-UT2 telescope) to obtain high-resolution spectra of 6 stars hosting transiting planets, namely for OGLE-TR-10, 56, 111, 113, 132 and TrES-1. The…
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…
