Color superconducting quark matter in compact stars
Matter just above nuclear density presents special challenges, both observational and theoretical. It is the densest state of which we have evidence in nature, but in terrestrial laboratories it can only be produced fleetingly and at high temperature over small volumes. We must therefore rely on astrophysical observations of compact stars to gather more indirect experimental information. Theore...
متن کاملDense quark matter in compact stars
The densest predicted state of matter is colour-superconducting quark matter, in which quarks near the Fermi surface form a condensate of Cooper pairs. This form of matter may well exist in the core of compact stars, and the search for signatures of its presence is an ongoing enterprise. Using a bag model of quark matter, I discuss the effects of colour superconductivity on the mass-radius rela...
متن کاملStrange Quark Matter and Compact Stars
Astrophysicists distinguish between three different kinds of compact stars. These are white dwarfs, neutron stars, and black holes. The former contain matter in one of the densest forms found in the Universe which, together with the unprecedented progress in observational astronomy, makes such stars superb astrophysical laboratories for a broad range of most striking physical phenomena. These r...
متن کاملCompact stars with color superconducting quark matter
We study compact stars that contain quark matter. We look at the effect of color superconductivity in the quark matter on the nuclear-quark matter transition density, mass-radius relationship, and the density discontinuity at the boundary between nuclear and quark matter. We find that color superconducting quark matter will occur in compact stars at values of the bag constant where ordinary qua...
متن کاملMetastable strange matter and compact quark stars
Strange quark matter in beta equilibrium at high densities is studied in a quark confinement model. Two equations of state are dynamically generated for the same set of model parameters used to describe the nucleon: one corresponds to a chiral restored phase with almost massless quarks and the other to a chiral broken phase. The chiral symmetric phase saturates at around five times the nuclear ...
