Bremsstrahlung radiation from vicinity of an object without events horizon
Abstract
It is follows from the observation data that the nonthermal radio source Sgr A* at the Galactic Center must be identified with a supermassive compact object with mass 2.6 x10^6 M_Sun. In paper (Verozub L.V., Kochetov A.Y, 2001) the existence of stable configurations of degenerated Fermi-gas without events horizon with masses 0^6 M_Sun - 10^9 M_Sun was argued. A spherically symmetric hydrodynamical accretion onto the object in the Galactic Center is considered in this paper. The profiles of the velocity, temperature and density in the falling gas have found taking into account of two-flow regime, dissipation processes, pressure of radiation and strong gravitation effects. The spectrum of the bremsstrahlung radiation is calculated. It is shown that the our results do not contradict the observation data.
