On dark stars, Planck cores and the nature of dark matter

Abstract: Dark stars are compact massive objects, described by Einstein gravitational field equations with matter. The type we consider possesses no event horizon, instead, there is a deep gravitational well with a very strong redshift factor. Observationally, dark stars can be identified with black holes. Inside dark stars, Planck density of matter is reached, Planck cores are formed, where the equations are modified by quantum gravity. In the paper, several models of dark stars with Planck cores are considered, result… Show more

“…A more accurate estimate is obtained from the fit of the MW rotation curve, the so-called Grand Rotation Curve (GRC, [44][45][46][47][48]). From this fit it can be seen, [1] Fig. 2, that on an approximately flat portion of the rotation curve at the position of the Sun r ∼ 8kpc there is a significant contribution of luminous matter, as a result of which the contribution of dark matter to v 2 is less than the trivial estimate.…”
