Scientists think they typically form as a kind of strange byproduct of a star's death, and end up orbiting a white dwarf. But a group led by David Champion of McGill University says that the new pulsar, PSR J1903+0327, actually orbits a Sun-like star. In other words, a star that hasn't gone supernova, blowing off its outer layers and condensing into a white dwarf or a neutron star. The new pulsar is also fast - it rotates every 2.15 milliseconds, or 465 times per second - which normally means it should be flying around its host in a circular orbit. But that's not the case here.
