Dark matter stars

TL;DR

This paper explores the properties of hypothetical dark matter stars composed of a cosmological SU(2)-weak gauge field, analyzing their structure, mass, radius, and energetic transitions through numerical solutions of stellar equations.

Contribution

It introduces a novel model of dark matter stars based on the CGF cosmology and solves their stellar structure equations numerically, revealing unique mass-radius relations and energetic phenomena.

Findings

Maximum star mass is approximately 9.14 micro solar masses.

Star radii range from 5.23cm to 13.6cm, with multiple radii possible for certain masses.

Transition between different radii releases about 10^{41} joules of energy.

Abstract

The dark matter in the CGF cosmology is a cosmological SU(2)-weak gauge field (the CGF). The TOV stellar structure equations are solved numerically for stars composed of this dark matter. The star mass M can take any value up to a maximum $9.14 \times 10^{-6}$ M_sun. For each value of M the star radius R lies between 5.23cm and 13.6cm. More than one value of R is possible when M > $5.09 \times 10^{-6}$ M_sun. For those stars, a transition from larger to smaller R would release gravitational energy on the order of $10^{41}$J in a time on the order of $10^{-10}$s.
