Equilibrium sequences of non rotating and rapidly rotating crystalline color superconducting hybrid stars
Nicola Ippolito, Marco Ruggieri, Dirk Rischke +2
The three-flavor crystalline color-superconducting (CCS) phase of quantum chromodynamics (QCD) is a candidate phase for the ground state of cold matter at moderate densities above…
Bulk viscosity of strange quark matter: Urca versus non-leptonic processes
Basil A. Sa'd, Igor A. Shovkovy, Dirk H. Rischke
A general formalism for calculating the bulk viscosity of strange quark matter is developed. Contrary to the common belief that the non-leptonic processes alone give the dominant c…
Bulk viscosity of spin-one color superconductors with two quark flavors
Basil A. Sa'd, Igor A. Shovkovy, Dirk H. Rischke
We consider the contribution of the Urca-type processes to the bulk viscosity of several spin-one color-superconducting phases of dense two-flavor quark matter. In the so-called tr…
