Study of the Ar()K reaction rate via proton scattering on K, and its impact on properties of modeled X-Ray bursts

A. Lauer-Coles, C. M. Deibel, J. C. Blackmon +21

Background: Type I X-Ray bursts (XRBs) are energetic stellar explosions that occur on the surface of a neutron star in an accreting binary system with a low-mass H/He-rich companio…

Beta-decay Half Lives beyond Ca: A Systematic Survey of Decay Properties approaching the Neutron Dripline

W. -J. Ong, Z. Y. Xu, R. Grzywacz +83

In an experiment performed at the Facility for Rare Isotope Beams (FRIB) using the FRIB Decay Station initiator (FDSi), 15 new half lives of isotopes near Ca were measured.…

Sensitivity of Nuclear Reaction Rates in X-ray Burst Models

I. Sultana, A. Estrade, B. S. Meyer +1

Type I X-ray bursts (XRBs) are thermonuclear runaways on the surface of accreting neutron stars, powered by rapid proton-capture and alpha-capture processes on neutron-deficient nu…

Crust composition and the Shallow Heat Source in KS 1731-260

R. Jain, E. F. Brown, H. Schatz +11

The presence of a strong shallow heat source of unknown origin in accreting neutron star crusts has been inferred by analyzing X-ray observations of their cooling in quiescence. We…

Machine-Learning-Enabled Measurements of Astrophysical (p,n) Reactions with the SECAR Recoil Separator

P. Tsintari, N. Dimitrakopoulos, R. Garg +29

The synthesis of heavy elements in supernovae is affected by low-energy (n,p) and (p,n) reactions on unstable nuclei, yet experimental data on such reaction rates are scarce. The S…

Enhanced production of 60Fe in massive stars

A. Spyrou, D. Richman, A. Couture +23

Massive stars are a major source of chemical elements in the cosmos, ejecting freshly produced nuclei through winds and core-collapse supernova explosions into the interstellar med…
