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.
