Abstract
It is shown that Rosen's bimetric theory of gravitation also has a Schwarzschild-type singularity. The radius of the singularity-the gravitational radius-is defined by the secondary massM 1. Simultaneously it is shown that only those configurations are stable, which are located in the range of central densities corresponding to the increasing branch of theM 1 =M 1(ρc) curve.
