Abstract With the launch of Chandra and XMM, many new and exciting observations of neutron stars are being made. Some of these observations have detected transient neutron stars cooling into quiescence. Transient neutron stars are a class of objects which are observed to go through accretion outburst periods followed by long quiescent intervals. These sources offer unique opportunities to probe the interior physics of neutron stars. In order to interpret these observations, accurate models of neutron star crusts are needed. In addition, experiments must be done to accurately determine the nuclear physics input for the calculations. A theoretical crust model was developed in this work to follow the evolution of the quiescent luminosity of a transiently accreting neutron star, and its results were compared with observations of two transient neutron stars: KS 1731-260 and MXB 1659-298. The comparison shows that the calculations for one set of parameters are consistent with observations of KS 1731-260, but under-predict the quiescent luminosity for MXB 1659-298. Additional physics is necessary to fully understand these systems. Constraints such as the conductivity of the crust and the material at
