Occultation of young stellar objects by circumstellar disks I. Theoretical expectations and preliminary comparison with observations

The hypothesis that partial occultation of young stars by their circumstellar disks is responsible for UX Ori and T Tauri Type III photometric variability is quantitatively studied. We construct accretion disk models in which reprocessing of stellar and accretion luminosity leads to flaring of the disk (assumed to be in vertical hydrostatic equilibrium), and compute the probability to observe t...

Pulsating Stellar Atmospheres

We review the basic concepts, present state of theoretical models, and the future prospects for theory and observations of pulsating stellar atmospheres. Our emphasis is on radially pulsating cool stars, which dynamic atmospheres provide a general example for the differences with standard static model atmospheres.

Stellar model atmospheres with magnetic line blanketing

Model atmospheres of A and B stars are computed taking into account magnetic line blanketing. These calculations are based on the new stellar model atmosphere code LLM which implements direct treatment of the opacities due to the bound-bound transitions and ensures an accurate and detailed description of the line absorption. The anomalous Zeeman effect was calculated for the field strength...
