Міра обертання радіовипромінювання пульсарів у декаметровому діапазоні

Abstract

The dissertation is devoted to the study of rapid changes in the rotation measure of radio radiation of pulsars closest to the Earth on short time scales in the decameter range. The dissertation proposes an original approach in which the parameters of the propagation medium are dynamically variable in the time scale of one pulse. This approach allows to analize the rapid processes in the upper layers of the magnetosphere of the pulsar and the pulsar wind. It is in these areas that the rotation measure, as a parameter describing the electron concentration and the magnetic field induction parallel to the line of sight, can vary depending on the phase of the individual pulse. The parameters of the radio propagation medium located further from the pulsar are stable at such time scales and cannot change so quickly.
