dc.description.abstract | Aims.The present paper describes the first results of an observational program intended to refine and extend the existing measurements of metal-poor stars, with an emphasis on field evolved stars. Methods.The survey was carried out with the FEROS and CORALIE spectrometers. For the measurements, obtained from spectral synthesis, we estimate an uncertainty of about 2.0. Results.Precise rotational velocities are presented for a large sample of 100 metal-poor stars, most of them evolving off the main–sequence. For the large majority of the stars composing the present sample, rotational velocities have been measured for the first time | pt_BR |
