Strange Quark Stars with a Rotating Superfluid Core
The generation of a magnetic field and its distribution inside a rotating bare strange quark star are discussed. It is shown that the difference between the angular velocities of the superfluid and superconducting quark core Ω s and of the normal electron plasma Ω n increases because of spin-down of...
