Data pubblicazione: | 2015 | Titolo del volume in cui è pubblicato il poster: | Twenty years of giant exoplanets - Proceedings of the Haute Provence Observatory Colloquium | Da pagina:: | 37 | Abstract: | We present a Bayesian homogeneous determination of orbital and physical parameters of a large sample of 211 giant transiting planets with masses between 0.1 and 24 M_{Jup} and precision on mass estimates better than 30%. We analyse new high-precision radial velocities for forty-five of them obtained with the HARPS-N@TNG spectrograph to improve and, in some cases, to revise the measure of their orbital eccentricity, and to search for long-period companions. From the updated orbital eccentricities we put constraints on the modified tidal quality factors of giant planets and their host stars. Our comprehensive study 1) allows for improved understanding of orbital evolution and migration scenarios for giant planets, and 2) provides the much needed benchmark statistics for thorough investigations of the diversity of giant planet densities and interior structures. | Titolo del convegno: | OHP 2015: Twenty Years of Giant Exoplanets | Luogo del convegno: | Observatoire de Haute Provence, France | Periodo del convegno: | 5-9 October, 2015 | URI: | http://hdl.handle.net/20.500.12386/28874 | URL: | https://ohp2015.sciencesconf.org/ | Bibcode ADS: | 2015tyge.conf...37B | Fulltext: | open |
