Contribution
It provides detailed calculations of neutrino emissivity and bulk viscosity for iso-CSL quark matter, aligning with astrophysical constraints and comparing with existing phases.
Findings
Iso-CSL phase satisfies cooling and rotational constraints.
Quantitative estimates of neutrino emissivity and bulk viscosity.
Comparison shows differences with 2SC+X phase.
Abstract
We present results for neutrino emissivities and bulk viscosities of a two-flavor color superconducting quark matter phase with isotropic color-spin-locked (iso-CSL) single-flavor pairing which fulfill the constraints on quark matter derived from cooling and rotational evolution of compact stars. We compare with results for the phenomenologically successful, but yet heuristic 2SC+X phase.
