Two-flavor Color Superconducting Quark Stars May Not Exist

The Astrophysical Journal
Large uncertainties in the determinations of the equation of state of dense stellar matter allow for the intriguing possibility that the bulk quark matter in beta equilibrium might be the true ground state of the matter at zero pressure.

Strange matter in compact stars

EPJ Web of Conferences, 2018
We discuss possible scenarios for the existence of strange matter in compact stars. The appearance of hyperons leads to a hyperon puzzle in ab-initio approaches based on effective baryon-baryon potentials but is not a severe problem in relativistic mean ...

Impact of the Nuclear Equation of State on the Stability of Hybrid Neutron Stars

Universe, 2019
We construct a set of equations of state (EoS) of dense and hot matter with a 1st order phase transition from a hadronic system to a deconfined quark matter state. In this two-phase approach, hadrons are described using the relativistic mean field theory

The Strange Prospects for Astrophysics

, 2009
The implications of the formation of strange quark matter in neutron stars and in core-collapse supernovae is discussed with special emphasis on the possibility of having a strong first order QCD phase transition at high baryon densities.

Superconducting quark matter

Nuclear Physics B, 1977
In asymptotically dense quark matter, colored glue forces cause an unusual variant of superconductivity. Instead of pairing, the quarks clump in groups of six. We investigate the gap equation in the weak coupling limit, and find the leading behavior of the energy gap and the critical temperature as functions of the renormalized coupling constant.

Quark matter — Facts and hopes [PDF]

Nuclear Physics A, 1989
Abstract The aim is to study nuclear matter under extreme conditions. The hope is that conditions reached in present relativistic heavy ion collisions are adequate for the formation of a quark-gluon plasma where colour would no longer be confined to hadronic dimensions. The situation prior to the “Quark Matter '88” conference is reviewed.
