Astrometry and Exoplanets: the Gaia Era, and Beyond
A. Sozzetti
The wealth of information in the Gaia catalogue of exoplanets will constitute a fundamental contribution to several hot topics of the astrophysics of planetary systems. I briefly r…
White Dwarf Planets from GAIA
Roberto Silvotti, Alessandro Sozzetti, Mario Lattanzi
We investigate the potential of high-precision astrometry with GAIA for detection of giant planetary companions to nearby white dwarfs. If one considers that, to date, no confirmed…
Photometric transit search for planets around cool stars from the Western Italian Alps: a site characterization study
M. Damasso, P. Giacobbe, P. Calcidese +5
We present the results of a site characterization study carried out at the Astronomical Observatory of the Autonomous Region of the Aosta Valley (OAVdA), in the Western Italian Alp…
Gaia and the Astrometry of Giant Planets
M. G. Lattanzi, A. Sozzetti
Scope of this contribution is twofold. First, it describes the potential of the global astrometry mission Gaia for detecting and measuring planetary systems based on detailed doubl…
Two new variable stars observed in the field of the extrasolar planet host star WASP-3
M. Damasso, A. Carbognani, P. Calcidese +6
We report the discovery of two new short-period variable stars in the Lyra constellation, GSC2.3 N208000326 and GSC2.3 N20B000251, observed at the Astronomical Observatory of Auton…
