J/ApJ/578/943    vsini of binaries with evolved component   (de Medeiros+, 2002)

The rotation of binary systems with evolved components. de Medeiros J.R., da Silva J.R.P., Maia M.R.G. <Astrophys. J. 578, 943 (2002)> =2002ApJ...578..943D
ADC_Keywords: Binaries, spectroscopic ; Stars, late-type ; Radial velocities ; Rotational velocities Keywords: binaries: spectroscopic - stars: fundamental parameters - stars: late-type - stars: rotation 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.
