К ТЕОРИИ ГЕНЕРАЦИИ ЭКВАТОРИАЛЬНОГО ШУМА В МАГНИТОСФЕРЕ ЗЕМЛИ
This work is devoted to the study of the generation of the equatorial noise—electromagnetic radiation below the LHR frequency observed near the equatorial plane of the magnetosphere at distances of ~4RE. According to accepted views, the generation of the equatorial noise is related to the instability of ring current protons. In this work, a logarithmic distribution of energetic protons over the magnetic moment with an empty loss cone is proposed, and arguments for the formation of such a distribution are presented. The main result of the work is the calculation and analysis of the instability increment of waves forming the equatorial noise. The increment obtained in this work significantly differs from that encountered in the literature.
