Abstract: |
By using the Monte Carlo radiative transfer code HDUST (developed by
A. C. Carciofi and J..E. Bjorkman) we have built a grid of models for stars presenting the B[e]
phenomenon and a bimodal outflowing envelope. The models are particularly
adapted to the study of B[e] supergiants and FS CMa type stars. The adopted
physical parameters of the calculated models make the grid well adapted to
interpret high angular and high spectral observations, in particular
spectro-interferometric data from ESO-VLTI instruments AMBER (near-IR at low
and medium spectral resolution) and MIDI (mid-IR at low spectral
resolution). The grid models include, for example, a central B star with
different effective temperatures, a gas (hydrogen) and silicate dust
circumstellar envelope with a bimodal mass loss presenting dust in the denser
equatorial regions. The HDUST grid models were pre-calculated using the high
performance parallel computing facility Mésocentre SIGAMM, located at OCA,
France. |
