# Gravitational effects of condensed dark matter on strange stars

## TL;DR

This study investigates how condensed dark matter, modeled as a Bose-Einstein condensate, influences the structure and maximum mass of strange stars, revealing that dark matter presence can make strange stars similar to neutron stars in size and mass.

## Contribution

It introduces a model of strange stars containing up to 4% dark matter as a Bose-Einstein condensate and analyzes their properties using the TOV equations.

## Key findings

- Dark matter presence affects star mass and radius.
- Strange stars with dark matter can reach neutron star-like masses.
- Dark matter particle mass influences star characteristics.

## Abstract

In the present work we study the gravitational effects of condensed dark matter on strange stars. We consider self-interacting dark matter particles with properties consistent with current observational constraints, and dark matter inside the star is modelled as a Bose-Einstein condensate. We integrate numerically the Tolman-Oppenheimer-Volkoff equations in the two-fluid formalism assuming that strange stars are made of up to 4 per cent of dark matter. It is shown that for a mass of the dark matter particles in the range $50 MeV-160 MeV$ strange stars are characterized by a maximum mass and radius similar to the ones found for neutron stars.
