Astronomy: A new twist on neutron stars

Theory suggests that neutron stars should be born rotating rapidly, but in reality they spin more slowly. New calculations suggest that they may be slowed by the emission of exotic gravity waves.

A neutron star is like a gigantic atomic nucleus, packing more than a solar mass of neutrons inside a ball just 20 kilometres across. Neutron stars are born when the iron core of a massive star collapses violently inside a supernova1.
