On dark stars, galactic rotation curves and fast radio bursts

This paper is a continuation of our recent work on Radial Dark Matter stars (RDM-stars), black holes, coupled with radial flows dark matter. As galaxy model, it produces flat rotation curves, approximately valid for many galaxies far from the center. In this paper, more detailed modeling carried out, including vicinity galactic Assuming that distribution stellar holes repeats luminous matter, we get perfect match between model curves and observed ones. Further, using numerical integration, examine gravitational field an individual RDM-star. The computation shows event horizon being erased rapidly increasing mass density arising instead (mass inflation). regime, apply previously constructed Planck star where at high densities repulsive force occurs (quantum bounce). stationary evolution has stopped under pressure matter flows. system considered as possible source Fast Radio Bursts (FRBs). scenario involving asteroid falling onto RDM-star, reproduces correct frequency range FRBs. Their total energy, coherence short duration are explained well.
