Be star models : observable effects of model parameters.

Abstract

We present the results for a large number of Be star models, detailing the influence of envelope density, temperature, and inclination on the Balmer line profiles, the line polarization, the continuum energy distribution, and the continuum polarization. We show that inclination effects are substantial, both in the emission lines and in the continuum. Changes in the envelope density and temperature also have a dramatic effect on the lines and the continuum. It is shown that any small set of observable features does not specify a unique model. We suggest a variety of observable features which appear to be most sensitive to model parameters. Subject headings: line formation - polarization - stars: atmospheres - stars: Be
