# Planck stars

@inproceedings{Rovelli2014PlanckS, title={Planck stars}, author={Carlo Rovelli and Francesca Vidotto}, year={2014} }

A star that collapses gravitationally can reach a further stage of its life, where quantum-gravitational pressure counteracts weight. The duration of this stage is very short in the star proper time, yielding a bounce, but extremely long seen from the outside, because of the huge gravitational time dilation. Since the onset of quantum-gravitational effects is governed by energy density —not by size— the star can be much larger than planckian in this phase. The object emerging at the end of the…

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

- Physics
- 2021

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…

### On dark stars, galactic rotation curves and fast radio bursts

- Physics

This paper is a continuation of our recent work on Radial Dark Matter stars (RDM-stars), black holes, coupled with radial flows of dark matter. As a galaxy model, it produces flat rotation curves,…

### RDM-stars as sources of fast radio bursts

- Physics
- 2018

In this work we consider a recently formulated model of a black hole coupled with radially directed flows of dark matter (RDM-star). In this model, a cutoff by quantum gravity (QG) creates a core of…

A gravitationally collapsed object can bounce-out from its horizon via a tunnelling process that violates the classical equations in a finite region. Since tunnelling is a non-perturbative…

### Effects of primordial black holes quantum gravity decay on galaxy clustering

- 2018

It has been recently suggested that small mass black holes (BHs) may become unstable due to quantum-gravitational effects and eventually decay, producing radiation, on a timescale shorter than the…
