"Photon emission from dense quark matter in compact stars"
Quark matter at large baryon density is characterised by
a colour-flavour-locked phase where chiral symmetry is
broken. This leads to the appearance of the light octet of
Goldstone bosons. At temperatures below the gap which
results from quark pairing, the light Goldstone bosons are
the dominant degrees of freedom and provide the main
source for photon emission. We calculate photon emission
rates from scattering of Goldstone bosons and discuss
possible observational consequences of our results for
compact stars featuring colour-superconductivity.
