The analysis of particles dynamics and its acceleration in the stellar magnetosphere under collapse show that the collapsing stars can by powerful sources of cosmic rays. The fluxes of cosmic rays from collapsing stars depend on its magnetic field and the initial particle spectrum in the magnetospheres. The collapsing stars can by also powerful sources of non-thermal radiation produced by the interaction of charged particles with the magnetic field. The effect can be observed by means of modern instruments. The particles acceleration and non-thermal emission in the magnetospheres of collapsing stars with initial dipole magnetic fields and a certain initial energy distribution of charged particles in a magnetosphere (power-series, relativistic Maxwell, and Boltzmann distributions) are considered. Collapse begins when the mass of stellar core exceeds the Chandrasekhar bound, and the star become dynamically unstable. When the star magnetosphere compressing under the collapse its magnetic field considerably increases. The cyclic electric field thus produced involving acceleration of charged particles. These particles will be generated radiation when moving in the magnetic field.
