Description
Type I X-ray bursts provide an important site for rp-process nucleosynthesis, where reaction flows are strongly influenced by nuclear masses, beta-decay lifetimes, and possible isomeric states. In this talk, I will present recent studies on the impact of new precision mass measurements, including 70Kr near the 68Se waiting point and nuclei in the A~90–100 region, on X-ray burst light curves and final ashes. I will also discuss how low-lying nuclear isomers may modify effective stellar reaction flows and introduce additional uncertainties or pathways in explosive nucleosynthesis.
