title = "Improved nuclear physics near A=61 refines urca neutrino luminosities in accreted neutron star crusts",
abstract = "We performed Penning trap mass measurements for Zn61 at the National Superconducting Cyclotron Laboratory and NuShellX calculations of the Zn61 and Ga62 structure using the GXPF1A Hamiltonian to obtain improved estimates of the Zn61(p,?)Ga62 and Cu60(p,?)Zn61 reaction rates. Surveying astrophysical conditions for type-I x-ray bursts with the code mesa, implementing our improved reaction rates, and taking into account updated nuclear masses for V61 and Cr61 from the recent literature, we refine the neutrino luminosity from the important mass number A=61 urca cooling source in accreted neutron-star crusts. This improves our understanding of the thermal barrier between deep heating in the crust and the shallow depths where extra heat is needed to explain x-ray superbursts, as well as the expected signature of crust urca neutrino emission in light curves of cooling transients.",
