EXODAT - The Exoplanets Database from the COROT Project : Evolution and Updates
No full textInternational audienceThe extended searches for exoplanets carried out over large samples of the stellar population raised new needs. A deep investigation in the nature and origin of the new planet population could be foreseen only on a well-characterized stellar population. LAM is part of the COROT exoplanet search and the SPHERE project. Two information systems have been implemented based on the SITools framework (http://vds.cnes.fr/sitools/tech.htm. Most of the databases include data with extra information processed at LAM: astrophysical quantities and statistical results, cross-identification algorithms, rotation curves. The goal of the databases from LAM is not only to provide data but valuable information on these data. While some data will soon be released to the community, we present the last updates of the EXODAT Information System including specific conesearch and free VO access to the community. The released spectra, images, footprints, and data will be provided throughout the EXODAT information System
Overview of CeSAM Tools and Services for the CoRoT Mission
No full textInternational audienceCoRoT (Convection Rotation et Transits planétaires) is a space mission of astronomy led by French space agency (CNES) in association with French laboratories (CNRS). One of CoRoT goal is to detect exoplanets by transit method. Since the beginning of the CoRoT project, the Centre de donnéeS Astrophysique de Marseille (CeSAM) is involved in many fields of activities: database, information system, software development and scientific analysis. We present some CeSAM implications
Exo-Dat: An Information System in Support of the CoRoT/Exoplanet Science
No full textInternational audienceExo-Dat is a database and an information system created primarily in support of the exoplanet program of the COnvection ROtation \amp planetary Transits (CoRoT) mission. In the directions of CoRoT pointings, it provides a united interface to several sets of data: stellar published catalogs, photometric and spectroscopic data obtained during the mission preparation, results from the mission and from follow-up observations, and several mission-specific technical parameters. The new photometric data constitute the subcatalog Exo-Cat, and give consistent 4-color photometry of 14.0 million stars with a completeness to 19th magnitude in the r-filter. It covers several zones in the galactic plane around CoRoT pointings, with a total area of 209 deg^2. This Exo-Dat information system provides essential technical support to the ongoing CoRoT light-curve analyses and ground-based follow-up by supplying additional complementary information such as the prior knowledge of the star's fundamental parameters or its contamination level inside the large CoRoT photometric mask. The database is fully interfaced with VO tools and thus benefits from existing visualization and analysis tools like TOPCAT or ALADIN. It is accessible to the CoRoT community through the Web, and will be gradually opened to the public. It is the ideal tool to prepare the foreseen statistical studies of the properties of the exoplanetary systems. As a VO-compliant system, such analyses could thus benefit from the most up-to-date classifier tools. The CoRoT space mission, launched on 2006 December 27, has been developed and is operated by CNES, with the contribution of Austria, Belgium, Brazil, ESA, Germany, and Spain. This project has made use of various observations collected with the Isaac Newton Telescope at La Palma and the GIRAFFE and UVES/FLAMES spectrographs at the VLT/UT2 Kueyen telescope (Paranal observatory, ESO, Chile: program 074.C-0633A, 081.C-0413)
