In the bimetric general relativity theory, one can have a collapsed star, filling its Schwarzschild sphere in hydrostatic equilibrium. Particles and light rays falling toward it bounce back from its surface. If it is surrounded by a cloud of gas, the falling particles may lose energy by collisions, thus arriving at the stellar surface with zero velocity so that they are accreted by the star. In this way the star may grow by mass accretion. This growth is simulated by a sequence of hydrostatic models leading from the initial to the final state of the star.
