Abstract:
In the present study we analyze the behavior of the rotational
velocity, vsini, for a large sample of 134 spectroscopic binary
systems with a giant star component of luminosity class III, along the
spectral region from middle F to middle K.
Description:
The observations were carried out with the CORAVEL spectrometer mounted
on the 1.0m Swiss telescope at the Haute-Provence Observatory, France
and on the 1.44m Danish telescope at ESO observatory, Chile, between
1986 March and 1994 January.
