SUMMARY:Quark Matter in Neutron Stars\, NPAC (Nuclear/Particle/Astro/C
 osmo) Forum\, Mark Alford\, Washington University
DESCRIPTION:Quark matter at high density and low temperature is expect
 ed to be a color superconductor\, which is a degenerate Fermi gas of q
 uarks with a condensate of Cooper pairs near the Fermi surface.  At th
 e highest densities\, where the QCD coupling is weak\, rigorous calcul
 ations are possible\, and the ground state is a particularly symmetric
  state\, the color-flavor locked (CFL) phase.  At lower densities the 
 CFL phase suffers from flavor-symmetry-breaking stresses\, so alternat
 ive phases\,<br>
\nsome of which break translation and/or rotation inv
 ariance\, may be favored. I will review the state of our understanding
  of these phenomena\, and discuss the effort to develop signatures of 
 the presence of color superconducting quark matter in neutron stars.<b
