Abstract |
Cosmic rays acceleration in the magnetosphere of collapsing stars and there electromagnetic radiation is considered. Cosmic rays will accelerate in magnetosphere of collapsing star, where the stellar magnetic field increases during the collapse and the charged particles are accelerated. The initial magnetospheres of collapsing star consist with protons and electrons. These particles accelerate during collapse to relativistic energy. Interacting among themselves and the magnetic fields in magnetosphere, these particles will lose their energy on the ionization and radiation. Electrons will be loss the energy with the most speed, and therefore the electrons lifetime is substantially smaller from the protons lifetime. As result the initial electrons will be loss their energy very fast. At the same time in the magnetosphere of collapsing stars will generate the secondary particles namely electrons, protons, neutrons, mesons, neutrino and photons. During the cascade interaction the secondary particles will generate the other particles and photons. Thus on the later stage of collapse the magnetosphere of collapsing stars consist with the particles and photons generating by multiple interaction of particles. The analysis of dynamics and emission of particles in the stellar magnetosphere under collapse shows that collapsing stars can by powerful sources of relativistic jets. These jets will generate non-thermal radiation. |
