Corot/SWG Progress Report Toward selection of the long run fields Corot-Week 5, Berlin, of dec STILL

E. Michel COROT Week 5, Berlin, dec. 03 E. Michel COROT Week 5, Berlin, dec. 03 These documents are a summary of what has been presented at CW5 for the SWG session report. The lists of candidate targets were discussed essentially on criteria regarding the Corot seismology programme. They will be reconsidered soon in order to take into account criteria of the exoplanet programme presented at CW5. Forwords

E. Michel COROT Week 5, Berlin,10-12 dec. 03 E. Michel COROT Week 5, Berlin,10-12 dec. 03 Data analysis:  solar-like principal candidates :Splitting and inclination. J. Ballot et al., H&H3 Seismic interpretation and diagnostics:  solar-like cand. S. Vauclair et al. ; A. Mazumdar et al.;R, Samadi et al.,… Modelling:  Fast rotation: Perturbative & diff. rot J.C. Suarez; nonpert F. Lignieres)  excitation & instability (A. Grigahcene et al.)

E. Michel COROT Week 5, Berlin, dec. 03 E. Michel COROT Week 5, Berlin, dec. 03 Corot field selection process:  Primary candidates: A star with known planets (G. Vauclair),A Beta Ceph. New candidate (C. Aerts et al.)  Secondary candidates: DSROs E. Poretti et al., Be puls. J. Fabregat, ; J. Gutierrez-Soto et al., L. Andrade;HgMn: G. Alecian… observations from the ground:  HARPS performances: F. Bouchy et al.
