... Head of the seminar: Prof. B.V. Somov, . ... The seminar considers the questions related to generation of magnetic fields in astrophysical plasmas, effect of the magnetic reconnection and particle acceleration in strong magnetic fields, the origin and propagation of cosmic rays, the flares and other non-stationary phenomena in the solar atmosphere and solar wind, Sun Earth connections and physical processes in the heliosphere. ... On the Topological Models and Topological Trigger of the Solar Flares...

... The circumnuclear GASEOUS disks are often decoupled from the circumnuclear stellar disks and are even stronger inclined to the outer disk planes; in fact, we have found a considerable `population' of inner polar rings. Inner gas polar rings are found as in spiral galaxies with the massive outer gas disks co-planar to the main symmetry planes (e.g. NGC 2841, Sil'chenko et al. 1997, and NGC 7217, Sil'chenko & Afanasiev 2000) as well in many lenticular galaxies (Fig. ...
