"Neutron stars as billion degree superconductors," May 3, 2013, 12n, MH 606

Neutron stars are highly compact remnants of a supernova explosion and display several amazing and extreme properties. Their core density can be much higher than the density of an atomic nucleus and under such enormous pressure, new phases of matter become thermodynamically favorable. One such phase is superconducting quark matter, which unlike terrestrial materials, is superconducting at even a billion degrees. Though made up of quarks, it can potentially display familiar features of electronic systems such as long-range order, ferromagnetism and gapless superconductivity. We will discuss the emergence and implications of these novel phases for neutron star phenomena from physical parameters like mass-radius properties and rotation rates to more subtle signals like neutrino bursts and gravitational waves.
