There has been much recent progress in our understanding of quark matter, culminating in the discovery that if such matter exists in the cores of neutron stars it ought to be in a color superconducting state. This paper explores the impact of superconducting quark matter on the properties (e.g., masses, radii, surface gravity, photon emission) of compact stars.
Astrophysicists distinguish between three different types 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. This feature, together with the unprecedented progress in observational astronomy, makes such stars superb astrophysical laboratories for a broad range of exciting physical studies. This article studies the role of strangeness for compact star phenomenology. Strangeness is carried by hyperons, mesons, H-dibaryons, and strange quark matter, and may leave its mark in the masses, radii, cooling behavior, surface composition and the spin evolution of compact stars.
