Previously it was shown that gravitation theory allows the existance of supermassive stable compact configurations of the degenerated electronic ga s (L.V.Verozub, Astr. Nacr. 317 (1996) 107 ) without events horizon. In the present paper the simplest model of such kind of objects in gas environment has been considered. It is shown that at the spherically symmetric accretio n onto the object the luminosity is about 1037 erg/s for the mass accret ionrate of the order of \stackrel*M=3D10-6 M_o/year . The vawelength of the radiation maximum is about 400\div 500 \stackreloA. There is an ionization zone around the central objects with the radius about 10-3pc.
