Descripción
In an earlier attempt to explain the observed excess in the IR flux of Be stars, we have analyzed the dielectronic recombination (DR) of Mg II in stellar envelopes and the influence of this atomic process on the stellar flux. In the present paper, we study the DR of other ions with astrophysical significance, namely, Si II and Si III, and reach the conclusion that Si II may also contribute to the IR excess in Be stars.
