Electromagnetic Radiation from Accretion-Induced Collapse of a White Dwarf

Abstract

The test for search of the accretion-induced collapse of a white dwarfs is proposed, using the non-thermal emission from their magnetosphere. This emission generate when the white dwarf magnetosphere compress during collapse and its magnetic field increase considerable. The produced electric field will accelerate of charged particles to relativistic energy. These particles will generated the non-thermal radiation moving in the magnetic field. We consider the particles dynamics and their non-thermal emission in the magnetosphere of the white dwarf with initial dipole magnetic fields and a certain initial energy distribution of charged particles in a magnetosphere (power-series, relativistic Maxwell, and Boltzmann distributions).
