Experimental constraints to nuclear processes in accreting neutron stars

Low-mass X-ray binaries are systems rich in observational phenomena valuable to constrain theoretical models of neutron stars and matter in extreme density environments. Several of these phenomena have an origin on nuclear processes that involve unstable isotopes, both on the neutron-rich and proton-rich side of beta-stability. A new generation of experimental facilities, such as the Facility for Rare Isotope Beams (FRIB), will make many of these short-lived isotopes accessible to experiments for the first time. We will discuss a reaction network calculation performed to evaluate how the uncertainty of nuclear reaction rates for proton-rich isotopes affect models for the nuclear processes driving type I X-ray bursts. We will also discuss recent results and plans of our program of mass measurements of neutron-rich isotopes, which are key to understand the nuclear composition and thermal profile of neutron star crusts.
