Discrepancy between infrared and optical emission in some Be stars
Liu, QZ; Wei, JY
AbstractAn expanding ring model is put forward to investigate the original regions of Halpha line emission and infrared excess emission in Be stars, by taking optical depth into account. We find that the two regions depend strongly on the physical properties of the envelope of Be stars such as the initial density and density structure. This model can be used to qualitatively interpret the disagreement between the near infrared excess and the equivalent width (EW) of Halpha emission line, as observed in some Be stars.
