ResumoStrange matter is quark matter that is assumed to be absolutely stable. A seed of strange matter in a neutron star will convert the star into a strange star. The speed at which this conversion occurs is calculated. The calculation takes into account the rate at which the down- and strange-quark Fermi seas equilibrate via weak interactions and the diffusion of strange quarks towards the conversion front. The speed is found as a function of the temperature of the star and the minimum strangeness necessary for strange matter stability. The conversion can be detected as an energy release of ∼58 MeV with different luminosities for different stages of a neutron star's evolution and as a "super-glitch" on pulsars' frequencies.
