Black holes or supermassive compact objects without event horizon?

It was previously shown that our gravitation equations [1] lead to the existence of supermassive stable compact configurations of degenerated electronic gas [2],[3] without an event horizon. In the present paper the simplest model of such objects in a gas environment has been considered. It is shown that for spherically symmetric accretion onto the object the luminosity is about 10(37) erg/s for a mass accretion rate of the order of M = 10(-6) M-circle dot/year. The wavelength of the radiation maximum is 400 - -500 Angstrom. There is an ionization zone around the central objects.
