Abstract

The thermal evolution of young neutron stars (NSs) reflects the neutrino emission properties of their cores. Heinke &amp; Ho (2010) measured a 3.6+/-0.6% decay in the surface temperature of the Cassiopeia A (Cas A) NS between 2000 and 2009, using archival data from the Chandra X-ray Observatory ...
