Abstract:
Precise rotational velocities vsini are presented for a large sample
of 100 metal-poor stars, most of them evolving off the main-sequence.
The survey was carried out with the FEROS and CORALIE spectrometers.
For the vsini measurements, obtained from spectral synthesis, we
estimate an uncertainty of about 2.0km/s. For the large majority of
the stars composing the present sample rotational velocities have been
measured for the first time.
Description:
The survey was carried out with the FEROS and CORALIE spectrometers.
For the vsini measurements, obtained from spectral synthesis, we
estimate an uncertainty of about 2.0km/s.
