We present a computing code for modelling energy flux distributions, photometric indices and spectral line profiles of (non-)radially pulsating Main-Sequence stars. ... In the case of slowly rotating stars one can use the zero-rotation approximation to describe stellar pulsations. Such a model was used already by Cugier, Dziembowski & Pamyatnykh (1994) to study nonadiabatic observables of Cephei stars. ...

Top] [Prev] [Next] . Serpens SVS 20 is a binary pre-main sequence star, whose components are separated by 1.5 arcsec. Although of very different brightness, both components have the same spectral energy distribution in the range 0.9 to 5 microns. Eiroa and Casali (1992) discovered that SVS 20 had a arc-shaped nebulosity, departing from the binary star towards the southwest. ...
