Vortex Dynamics in Color-Superconducting Quark stars: The Re-heating of Magnetars

摘要: Compact stars made of quark matter rather than confined hadronic matter, are expected to form a color superconductor. This superconductor ought be threaded with rotational vortex lines within which the star's interior magnetic field is confined. The vortices (and thus flux) would expelled from star during stellar spin-down, leading reconnection at surface and prolific production thermal energy. In this Letter, we show that energy release can re-heat exceptionally high temperatures, such as observed for Soft Gamma Repeaters (SGRs), Anomalous X-Ray pulsars (AXPs), X-ray dim isolated neutron (XDINs). Moreover, our numerical investigations temperature evolution, spin-down rate, behavior superconducting suggest SGRs, AXPs, XDINs may linked ancestrally. Finally, discuss possibility time delay before enters phase, used estimate density quarks deconfine. We find five times nuclear saturation.
