Modern compact star observations and the quark matter EoS
A hybrid equation of state (EoS) for dense matter is presented that satisfies phenomenological constraints from modern compact star (CS) observations which indicate high maximum masses (M ∼ 2M⊙) and large radii (R > 12 km). The corresponding isospin symmetric EoS is consistent with flow data analyses of heavy-ion collisions. The transition from nuclear to two-flavor color superconducting quark ...
متن کاملCompact star constraints on the high-density EoS
A new scheme for testing the nuclear matter (NM) equation of state (EoS) at high densities using constraints from compact star (CS) phenomenology is applied to neutron stars with a core of deconfined quark matter (QM). An acceptable EoS shall not to be in conflict with the mass measurement of 2.1 ± 0.2 M⊙ (1 σ level) for PSR J0751+1807 and the mass-radius relation deduced from the thermal emiss...
متن کاملThermodynamics of compact - star matter within an Ising approach
In the formation and evolution of compact stars, nuclear matter explores high thermal excursions and is the site of intense neutrino emission. Neutrino transport as well as structural properties of this matter depend on the presence of inhomogeneous phases (named " pasta " phases), which are the result of Coulomb frustration of the Liquid-Gas phase transition. We take into account charge fluctu...
متن کاملScaling relations in dynamical evolution of star clusters
We have carried out a series of small scale collisional N-body calculations of single-mass star clusters to investigate the dependence of the lifetime of star clusters on their initial parameters. Our models move through an external galaxy potential with a logarithmic density profile and they are limited by a cut-off radius. In order to find scaling relations between the lifetime of star cluste...
متن کاملNuclear matter EOS with a three-body force
The effect of a microscopic three-body force on the saturation properties of nuclear matter is studied within the Brueckner-Hartree-Fock approach. The calculations show a decisive improvement of the saturation density along with an overall agreement with the empirical saturation point. With the three-body force the symmetry energy turns more rapidly increasing with density, which allows for the...
