Mass and Radius Relations of Quarkyonic Stars Using an Excluded-volume Model

Inspired by the excluded volume model for isospin symmetric quarkyonic matter, we construct an `excluded volume' a charge neutral phase whose hadronic sector contains only neutrons. We refer to this as neutron matter. compute equation of state and solve Tolman-Oppenhermer-Volkoff equations obtain mass radius relations relevant stars. The most straightforward extension matter does not satisfy constraints from star measurements. However, show that incorporating appropriate nuclear interactions in one can produce mass-radius lie within obtained gravitational waves binary mergers maximum measurements
