Australia-based scientists have found a star named Regulus, about 79 light-years away, spins at about 320 kilometres per second. The spin rate is 96.5% of the angular velocity for the break-up, said scientists. Further, it is the first observed to emit polarised light, a phenomenon predicted for rapidly-rotating stars by Indian astrophysicist and Nobel laureate Subrahmanyan Chandrasekhar in 1946.
