... The picture shows a 2-dimensional sketch of the outflowing wind of a quasar (Elvis 2000, Astrophysical Journal , vol.545, p.63-76). In the funnel-shaped disk wind Elvis (2000) model a wind arises from a restricted range of radii on the accretion disk around the central black hole. Initially the wind makes a large angle to the disk plane (and so is roughly cylindrical). ... Looking through the quasi-cylindrical part of the wind we see UV and X-ray warm absorbers. ...

Next: Identification and Analysis of Binary Star Systems using Probability Theory . ... 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. ...

... The spectrum of the brightest star, our Sun, shows several dark gaps perpendicular to the flow of it’s colours (figure 1). These so called spectral absorption lines where discovered in 1802 by the English scientist William Wollaston. ... Some stars as Pollux show a spectrum similar to that of our sun with strong Ca II and Fe II lines, others as Sirius or Vega show strong absorption lines of hydrogen, others, as Mira show very complicated spectra due to molecular absorption lines (see figure 5). ...
