3C58 or 3C 58 is a pulsar (with the designation PSR J0205 + 6449) and a supernova remnant ( pulsar wind nebula ) in the Milky Way , which is possibly connected to the supernova 1181 . However, there are indications of an age of several thousand years, which would rule out a connection with the supernova.
3C 58 is notable for its high cooling rate, which does not correspond to the standard theories about the formation of neutron stars . According to one hypothesis , it is believed that extreme conditions inside the star cause a high flux of neutrinos , which carries away the energy and cools the star.
The pulsar is in the direction of the Cassiopeia constellation and is about 10,000 light years away from us. Its rotation period is 65.7 milliseconds .
3C 58 could be a quark star .
