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…
On the nature of Lithium-rich giant stars: constraints from Beryllium abundances
C. H. F. Melo, P. de Laverny, N. C. Santos +4
We have derived beryllium abundances for 7 Li-rich giant (A(Li) > 1.5) stars and 10 other Li-normal giants, with the aim of investigating the origin of the Lithium in the Li-rich g…
A planet-sized transiting star around OGLE-TR-122 - Accurate mass and radius near the Hydrogen-burning limit
F. Pont, C. H. F. Melo, F. Bouchy +4
We report the discovery and characterisation of OGLE-TR-122b, the smallest main-sequence star to date with a direct radius determination. OGLE-TR-122b transits around its solar-typ…
Spectroscopic [Fe/H] for 98 extra-solar planet-host stars: Exploring the probability of planet formation
N. C. Santos, G. Israelian, M. Mayor
We present stellar parameters and metallicities, obtained from a detailed spectroscopic analysis, for a large sample of 98 stars known to be orbited by planetary mass companions (a…
The metal-rich nature of stars with planets
N. C. Santos, G. Israelian, M. Mayor
With the goal of confirming the metallicity "excess" present in stars with planetary-mass companions, we present in this paper a high-precision spectroscopic study of a sample of d…
