6. CoSADIE: The VO in Europe
Goal: Design a sustainable version of the already successful European Virtual Observatory (Euro-VO).
Work Packages:
WP1 - Management
WP2 - Increasing awareness and gathering requirements from the user and provider communities
WP3 - Coordinating technical activities and defining the technical needs to maintain the VO framework
WP4 - Outreach towards education and the general public interested in astronomy
WP5 - Strategy, governace and financial sustainability of Euro-VO

7. How can VO be of help to CoRoT?
Use case #1: Membership selection
The precise mechanisms governing angular momentum evolution of PMS low-mass stars are still not well understood,
On the other hand, the
observed existence of slow rotators and of a wide dispersion
in rotation rates of cluster stars on the zero-age main sequence
(ZAMS), can be explained only with the presence
of a competing mechanism of angular momentum loss (i.e.
spin down of the star), different from star to star, during
the pre-main sequence phase. It is generally believed that this mechanism can be explained by the magnetic interaction
between stellar magnetospheres and circumstellar disks
disks, in a scenario known as disk- locking, first

>17 million light curves
> 10 million objects
> 40 million objects

23. Summary esm@cab.inta-csic.es
There are many fields in which VO can help to exploit CoRoT data BUT...
There are still some caveats and your collaboration is essential (i.e., providing use cases covering news scenarios not yet contemplated)
