Planetology in VO: Activities in France (and elsewhere ?)J. Berthier, P. Didelon, P.Le Sidaner, A. Sarkissian, J.-M. Desert, G. Poulleau, J.-L. Orcesi, L. Chevalier, J. Schneider, Vachier, Thuillot, Lainey, Arlot et al.

  • Started after tutorial at CDS in October 2004 (but first discussions in Pune, September 2004, thanks VO-France)

  • Composed of 14 people, 5 labs, 5 On-line data-bases:

    IMCCE , OBSPM , IAS , IPSL-CDAP , CEA-Cassini

  • Objective : planetology in VO (or VO in planetology !)

  • Includes bodies of the solar system, exoplanets, surfaces, atmospheres, rings, etc…


Slide2 l.jpg

  • First discussions :

    • Missing definitions of meta-data for dynamics and photometry for bodies of solar system

    • Missing definitions of parameters commonly used in geophysics (planetary atmospheres, surface, sub-surface, etc…

  • First view :

    • PDS (Planetary Data System) --> VO seems ok, but a lot of work needed (CNES, started, first version soon )

    • Space Time Coordinate Needs modifs in VO

  • VO-planeto activities:

    • UCD : 13 to be submitted soon, 8 modifications

    • VO-table : Started,tutorial CDS, October 2004

  • VO-planeto activities:

    • UCD : 13 to be submitted soon, 8 modifications

    • VO-table : Started,tutorial CDS, October 2004

    • Data Model : next step, needs Tutorial (CDS)


Slide9 l.jpg

Extension of Activities:

Poster at EGU, Vienne, April 2005

38 authors, 14 labs, Institutions, etc..

7 databases with online data

+ VO-France

Links with Europlanet

-European project, support data bases

in planetology,

-more than 50 scientists,

-20 labs, 7 countries including

F, UK, D, I, S

Starting VO compatible applications

Expected results, end of 2005
