TL;DR
This paper explores the theoretical properties of dark matter stars with anisotropic pressures, providing exact solutions that are consistent within General Relativity and applicable to real astrophysical objects.
Contribution
It introduces the first exact analytical solutions for anisotropic dark matter stars, addressing a gap in modeling such exotic objects.
Findings
Solutions are well-behaved within General Relativity
Models can describe realistic astrophysical configurations
Anisotropies significantly affect star structure
Abstract
The properties of exotic stars are investigated. In particular, we study objects made entirely of dark matter and we take into account intrinsic anisotropies which have been ignored so far. We obtain exact analytical solutions to the structure equations and we we show that those solutions i) are well behaved within General Relativity, and ii) are capable of describing realistic astrophysical configurations.
