... Solar flare activity is produced by the processes of accumulation and release of energy in an active region. ... In the framework of study of solar active regions, producing powerful flares the researchers from the RATAN-600 radio telescope have detected sources with features in the form of a sharp drop in the intensity of polarized radiation in various parts of the recorded frequency range (2-16GHz), sometimes changing the sign of polarization. ...

We perent radio flux measurements at 5 GHz for a sample of RS CVn-type chromospherically active binary systems made from 1988 to 1992 using the NRAL broad-band interferometer (BBI). The derived radio luminosities are consistent with previous observations but show that radio flaring is a common feature which will affect the results of rotation-activity studies. ...

... My thesis aims to understand the energetics and composition of the jet near its origin, and its interaction with the ICM , focusing on detailed models of the inner structure of a spectacular radio source Hydra A. The key features of my modelling are that 1) I identify the four bright knots in the northern jet of Hydra A as biconical reconfinement shocks, which result when an over-pressured jet starts to come into equilibrium whit the galactic ...
