On dark stars, galactic rotation curves and fast radio bursts

چکیده
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.

Dark Matter and Rotation Curves of Stars in Galaxies
The dark matter accretion theory (around a central body) of the author on the basis of his 5-dimensional Projective Unified Field Theory (PUFT) is applied to the orbital motion of stars around the center of the Galaxy. The departure of the motion from Newtonian mechanics leads to approximately flat rotation curves being in rough accordance with the empirical facts. The spirality of the motion i...
متن کاملCosmology and Galactic Rotation Curves
We explore the possibility that the entire departure of galactic rotational velocities from their luminous Newtonian expectation be cosmological in origin, and show that within the framework of conformal gravity (but not Einstein gravity apparently) every static observer sees the overall Hubble flow as a local universal linear potential which is able to account for available data without any ne...
متن کاملFast radio bursts: the last sign of supramassive neutron stars
Context. Several fast radio bursts have been discovered recently, showing a bright, highly dispersed millisecond radio pulse. The pulses do not repeat and are not associated with a known pulsar or gamma-ray burst. The high dispersion suggests sources at cosmological distances, hence implying an extremely high radio luminosity, far larger than the power of single pulses from a pulsar. Aims. We s...
متن کاملFast radio bursts may originate from nearby flaring stars
Six cases of fast radio bursts (FRBs) have recently been discovered. The FRBs are bright (∼0.1–1 Jy) and brief (∼1 ms) pulses of radio emission with dispersion measures (DMs) that exceed Galactic values, and hence FRBs have been interpreted to be at cosmological distances. We propose, instead, that FRBs are rare eruptions of flaring main-sequence stars within ∼1 kpc. Rather than associating the...
متن کاملDark Baryons and Rotation Curves
The best measured rotation curve for any galaxy is that of the dwarf spiral DDO 154, which extends out to about 20 disk scale lengths. It provides an ideal laboratory for testing the universal density profile prediction from high resolution numerical simulations of hierarchical clustering in cold dark matter-dominated cosmological models. We find that the observed rotation curve cannot be fit e...
