  Neutron star X-ray binaries (NS XRBs) associated with supernova remnants
(SNRs) are the youngest X-ray binaries that can provide insights into the early
evolution of X-ray binaries and the formation properties of neutron stars.
There are an increasing number of NS XRBs discovered to be harbored in SNRs in
our and nearby galaxies. In this work, we perform binary population synthesis
calculations to simulate the population of NS XRBs associated with SNRs for
different types of companions, including Roche-lobe overfilling main-sequence
stars, Be stars and supergiants. We estimate their birthrates and present the
distributions of orbital parameters and companion mass for each type of
companions. Our calculations show that the majority of them are Be X-ray
binaries (BeXRBs) and that a few BeXRBs are expected to be associated with SNRs
in a Milky Way-type galaxy.
