Abstract:
Rotational and radial velocities have been measured for about 2000
evolved stars of luminosity classes IV, III, II and Ib covering the
spectral region F, G and K. The survey was carried out with the
CORAVEL spectrometer. The precision for the radial velocities is
better than 0.30km/s, whereas for the rotational velocity measurements
the uncertainties are typically 1.0km/s for subgiants and giants and
2.0km/s for class II giants and Ib supergiants. These data will add
constraints to studies of the rotational behaviour of evolved stars as
well as solid informations concerning the presence of external
rotational brakes, tidal interactions in evolved binary systems and on
the link between rotation, chemical abundance and stellar activity.
