SUMMARY:Cooling of the Cassiopeia A neutron star and superfluid implic
 ations \, Network in Neutrinos\, Nuclear Astrophysics\, and Symmetries
  (N3AS) Seminar\, Wynn Ho\, Haverford College
DESCRIPTION:Neutron stars are born extremely hot in the aftermath of a
  supernova and then cool by neutrino emission over the next million ye
 ars. Measurements of the temperature of neutron stars of various ages 
 provide crucial insights into nuclear physics that govern neutron star
  cooling\, such as proton-neutron asymmetry\, superfluidity\, and tran
 sitions to hyperons and deconfined quarks at high densities. Here I pr
 ovide an update on observations of the youngest neutron star known and
  its rapid cooling over 20 years and implications for neutron superflu
 idity and proton superconductivity.
