When stars reach the end of their main sequence, they undergo a gravitational collapse, ejecting their outermost layers in a supernova explosion.

An even rarer subset of neutron stars are magnetars, only two dozen of which are known in our galaxy.

Discovery of runaway companion star points to a mass-exchange during a supernova explosion; weird conditions that lead to the weird, violent object called a magnetar.
