Title of the communication: The electromagnetic burst shape from collapsing magnetized star.
Preliminary abstract (12 lines max.): The shape of magneto-dipole losses is investigating.For the first time, within the limits of the simple model, the burst like-type radiation is obtained both for a direct collapse and for a case of formation of a fast-rotating, self-gravitating object colled spinar, taking into account the main relativistic effect - the desappearance of magnetic field during the collapse to the black hole. The burst dependence on radius is analytically derived and the burst dependence on time for an infinitely far observer is simulated. The most interesting is the possibility of acceleration of particles up to Plank energies in the vicinity of the supermassive spinars. Astrophysical applications to the merging neutron stars, AGN and QSOs are briefly discussed.
