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 Extended Soft Approximation for Spherical Particles A.Y. Perelman St.Petersburg State Forest Technical Academy and N.V. Voshchinnikov Astronomy Department and Sobolev Astronomical Institute, St.Petersburg University Abstract The soft approximation (SA) gives the possibility to obtain the different optical characteristics of particles from the common point of view [1]. As for the Mie theory, they are expressed in terms of the scattering coefficients $a_n$ and $b_n$. ...

... It is found that the correlation coefficients between these two parameters calculated separately inside and outside the sunspot formation zone ±30 have cyclic variation and occur in anti-phase. This suggests different mechanisms of formation of the corona in the fields of small, medium, and large scales. ... The relationship between the coronal green line brightness (CGLB) and the magnetic field strength (MFS) has been investigated by constructing the corresponding synoptic maps for the 1977-2001. ...
