Modern compact star observations and the quark matter EoS
Abstract
A hybrid equation of state for dense matter is presented that satisfies phenomenological constraints from modern compact star observations which indicate high maximum masses of about 2 Msun and large radii of R> 12 km. The corresponding isospin symmetric equation of state is consistent with flow data analyses of heavy-ion collisions. The transition from nuclear to two-flavor color superconducting quark matter at n approximately 0.55 fm-3 is almost a crossover.
