Estimation of the mass loss, opening angle and mass of Be circumstellar disks from Brγ continuum emission and interferometric measurements.


Abstract (from CDS):

Using the SIMECA code developed by Stee & Araujo (1994A&A...292..221S); Stee et al. (1995A&A...300..219S) for Be stars we obtain a correlation between the mass loss rates {dot}(M) and the Brγ continuum luminosity as a function of the opening angle of the disk. We show that this correlation is similar to those obtained by Scuderi et al. (1998A&A...332..251S) for O-B supergiants. We found that the wind density at the base of the photosphere, from a sample of 8 Be stars, lies between 10–13 and 10–12g/cm3. We also present a relationship between the mass of the circumstellar disk and the 2.16µm flux. Finally we emphasize how interferometric measurements can help to estimate the wind density and we present a sample of 16 Be stars with predicted visibilities that can be observed with the VLTI.
