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. ...

X-ray astronomy primarily involves the study of plasmas with thermal temperatures in the range of 1E6 to 1E8 K. Such plasmas radiate the bulk of their energy in the X-ray regime, from ca. 0.1 to 10 keV. ... Apart from X-ray continuum emission, produced through processes such as e.g. thermal bremsstrahlung, a significant fraction of the total emissivity of hot thermal plasmas can arise from line emission. ...
