A biref summary on the recent result on compact star equation of state will be presented. I summarize the directions and activities of the NewCompStar working group on the physics of the strong interaction in cold dense nuclear and QCD medium exists in compact stars.
This talk will describe the continuing development of a consistent
picture of the liquid interiors of neutron stars, driven by three
recent advances: observations of heavy neutron stars with masses ~2.0
solar masses; determinations of masses and radii simultaneously for an
increasing number of neutron stars; and an emerging understanding in
QCD of how nuclear matter can turn into deconfined...
We delineate properties of cold, dense QCD matter through equations of state supposed from observational constraints on neutron stars.
We performed a Bayesian analysis of a new class realistic models of two-phase equations of state (EoS) for hybrid stars and demonstrated that the observation of such a pair of high-mass twin stars would have a sufficient discriminating power to favor hybrid EoS with a strong first order phase transition over alternative EoS.
The new class of two-phase EoS is characterized by three main...
