Abstract
We present a model of compact stars with a dark matter core. The hadronic equation of state is based on the parity doublet model and does not present a phase transition to quark matter. Instead, a strong first-order phase transition to dark matter described by a constant speed of sound model leads to the scenario of compact star mass twins. Compact star structural properties which obey state-of-the-art measurements and constraints are presented.
