Gravity seminar - Armen Sedrakian Seminar

 

I will discuss the properties of compact stars featuring color superconducting phases of dense QCD. This will include modeling of massive compact stars, neutrino cooling of such stars, and possible signatures of a phase transition within the QCD phase diagram in the X-ray data from the young neutron star in Cassiopeia A. I will go on and discuss the constraints on axions - hypothetical particles predicted to solve the strong CP problem in QCD - placed by the cooling simulations of neutron stars.
