A long-period massive planet around HD106515A
S. Desidera, R. Gratton, E. Carolo +9
We have performed RV monitoring of the components of the binary system HD 106515 over about 11 years using the high resolution spectrograph SARG at TNG. The primary shows long-peri…
Improved spectroscopic parameters for transiting planet hosts
Guillermo Torres, Debra A. Fischer, Alessandro Sozzetti +4
We report homogeneous spectroscopic determinations of the effective temperature, metallicity, and projected rotational velocity for the host stars of 56 transiting planets. Our ana…
The frequency of giant planets around metal-poor stars
A. Mortier, N. C. Santos, A. Sozzetti +4
Context. The discovery of about 700 extrasolar planets, so far, has lead to the first statistics concerning extrasolar planets. The presence of giant planets seems to depend on ste…
Gravitation Astrometric Measurement Experiment
Mario Gai, Alberto Vecchiato, Sebastiano Ligori +2
The Gravitation Astrometric Measurement Experiment (GAME) is a mission concept based on astronomical techniques (astrometry and coronagraphy) for Fundamental Physics measurements,…
Gaia Universe Model Snapshot : A statistical analysis of the expected contents of the Gaia catalogue
A. C. Robin, X. Luri, C. Reylé +17
Context. This study has been developed in the framework of the computational simulations executed for the preparation of the ESA Gaia astrometric mission. Aims. We focus on describ…
Astrometry and Exoplanet Characterization: Gaia and Its Pandora's Box
A. Sozzetti
In its all-sky survey, Gaia will monitor astrometrically hundreds of thousands of main-sequence stars within pc, looking for the presence of giant planetary companions…
