Scientific paper

We investigate the newtonian stationary accretion of a polytropic perfect
fluid onto a central body with a hard surface. The selfgravitation of the fluid
and its interaction with luminosity is included in the model. We find that for
a given luminosity, asymptotic mass and temperature of the fluid there exist
two solutions with different cores.
