The puzzling
phenomenon of pulsar kicks, i.e. the observed large escape velocities
of pulsars out of supernova remnants, is examined for compact stars
with a strange quark matter core.
The direct urca process in quark matter is studied in the presence
of a strong magnetic field.
Conditions for an asymmetric emission of the produced neutrinos are
worked out in detail, giving constraints on the temperature, the strength
of the magnetic field and the electron chemical potential in the quark
matter core.
In addition, the neutrino
mean free paths for quark matter and a possible hadronic mantle are
considered.
We find that highly magnetized colour-flavour locked quark matter in
a hot proto-neutron star
can signal itself by a sizable kick velocity of the pulsar.
