  1. A complement to the COROT photometric time-series will be very useful, mandatory in some cases We need the intensive use of ground based facilities to be really complementary

  2. Study of DSCT, GDOR, BCEP,SPB, Be stars LPV with different approaches (data sharing) Mode identification (spectoscopy and photometry) Determination of the rotational period Study of solar-like oscillations in F-G stars Studied with HARPS from ground. Well-established know-how. Essentially RV measurements Magnetic activity of F-G stars Zeeman-Doppler imaging map Evaluation of the stellar activity to interpret pulsation Better modelization knowing convection Rotation, also differential Interferometric observations Angular diameters

  3. It looks very complicated to apply for observing time answering to normal calls. It should be possible by answering to LARGE PROGRAMMES calls. We need tens of night in each semester We need a sort of agreement with Observatories (ESO, TNG, CFHT, OHP, TBL,…) to have dedicated time for COROT targets. We have to support our request justifying both the scientific case and the number of nights. A document should be issued before end of September (under the responsability of Claude Catala)

  4. Study of DCST, GDOR, BCEP, SPB, Be stars ESO : FEROS OHP : ELODIE CFHT : ESPADONS Study of solar-like oscillations in F-G stars ESO : HARPS TNG : SARG (RV mode) Magnetic activity of F-G stars TNG : SARG (spectropolarimetry mode) CFHT : ESPADONS TBL : NARVAL Interferometric observations ESO : AMBER/VLTI
