How does dark matter affect compact star properties and high density constraints of strongly interacting matter

Understand

We study the impact of asymmetric bosonic dark matter on neutron star properties, including possible changes of tidal deformability, maximum mass, radius, and matter distribution inside the star.

• The conditions at which dark matter particles tend to condensate in the star's core or create an extended halo are presented.
• We show that dark matter condensed in a core leads to a decrease of the total gravitational mass and tidal deformability compared to a pure baryonic star, which we will perceive as an effective softening of the equation of state.
• On the other hand, the presence of a dark matter halo increases those observable quantities.
