J/A+A/368/912  Polarization and rotational velocities of Be stars (Yudin, 2001)

Statistical analysis of intrinsic polarization, IR excess and projected rotational velocity distributions of classical Be stars. Yudin R.V. <Astron. Astrophys. 368, 912 (2001)> =2001A&A...368..912Y
ADC_Keywords: Stars, Be ; Polarization ; Rotational velocities Keywords: classical Be stars: polarization - projected rotational velocities - near IR excesses - far IR excesses Abstract: We present the results of statistical analyses of a sample of 628 Be stars. The parameters of intrinsic polarization p*, projected rotational velocity (vsini), and near IR excesses have been investigated. The values of p* have been estimated for a much larger and more representative sample of Be stars (∼490 objects) than previously. File Summary:
