Supernova to superfluid
Neutron stars may be cooled by frictionless liquid
By Devin Powell, 14:53 PM February 4, 2011
Neutron stars, second only to black holes and pints of Guinness as the densest objects in the Universe, may have liquid in their cores, observations of a dead star shrouded in the debris of a distant supernova suggest. Two separate teams of scientists say that a frictionless state of matter called a superfluid is the only reasonable explanation for temperature changes recently observed in the youngest known neutron star.
“This the first direct evidence for superfluidity in neutron stars,” says...
