Description
We present a field-theoretic analysis of neutrino emission from dense quark matter in strong magnetic fields, focusing on conditions relevant to magnetar interiors. In the unpaired quark phase, we study both direct Urca and synchrotron processes. For the Urca process, we develop an approximation that includes Landau quantization for electrons but not quarks, which is appropriate for high-density matter. This reveals anisotropic and field-dependent emission rates with potential consequences for magnetar cooling and pulsar kicks. Although subdominant, synchrotron emission offers insight into the magnetic-field-driven dynamics of quark matter. Our results underscore the complex role of magnetic fields in neutrino production from magnetized quark cores.
