arXiv:0705.1648 [ps, pdf, other] : Title: Extralong X-ray Plateau in GRB and Spinar Paradigm

The recently discovered gamma-ray burst GRB 070110 displayed an extraordinary x-ray afterglow with x-ray radiation -- x-ray plateau -- observed for 20000 seconds. We show that the observed properties of the plateau can be naturally interpreted in terms of the model with a spinar -- a quasi-equilibrium collapsing object whose equilibrium is maintained by the balance of centrifugal and gravitational forces and whose evolution is determined by its magnetic field. Moreover, x-ray telescopes during one hour have recorded radiation from an object whose size was smaller than the Schwartaschield radius!
