  In this paper, we present an inference method for determining neutron star
parameters and constraining the nuclear equation of state (EOS) using the RIFT
parameter inference engine. We incorporate externally-produced prior
information about the EOS to improve the accuracy and efficiency of the
inference process. We apply this method to the GW170817 event and assess its
performance. Our results demonstrate the effectiveness of incorporating prior
EOS information in the inference process, leading to sharper conclusions and
more rapid inference on new detections. This approach has the potential to
enhance our understanding of neutron stars and the nuclear EOS in future
gravitational wave observations.
