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.
