Possible Phase Transitions from Hadronic to Quark Matter Inside Neutron

Neutron stars are unique laboratories for the investigation of the high-density properties of bulk matter. In this talk, we examine the astrophysical constraints on a phase transition from hadronic matter to deconfined quark matter. A parameterizable relativistic mean field equation in compliance with chiral effective field theory results is used, where the stiffness of the equation of state can be varied via the effective mass at saturation density. The phase transitions are modeled using a Maxwell construction and assumed to be of first order. Regions in the parameter space of the transition that could provide an indication of a phase transition in the near future are outlined.
