Short-lived Population III stars suppress the high-redshift TDE rate, and dark matter annihilation near a particle mass of 1 MeV can revive the rate by extending stellar lifetimes.

abstract
We announce the public release of the 'dark' stellar evolution code DarkStars. The code simultaneously solves the equations of WIMP capture and annihilation in a star with those of stellar evolution assuming approximate hydrostatic equilibrium. DarkStars includes the most extensive WIMP microphysics of any dark evolution code to date. The code employs detailed treatments of the capture process from a range of WIMP velocity distributions, as well as composite WIMP distribution and conductive energy transport schemes based on the WIMP mean-free path in the star. We give a brief description of the input physics and practical usage of the code, as well as examples of its application to dark stars at the Galactic centre.

Dark Matter-Powered Stars and the High-Redshift Tidal Disruption Event Rate
Short-lived Population III stars suppress the high-redshift TDE rate, and dark matter annihilation near a particle mass of 1 MeV can revive the rate by extending stellar lifetimes.
