Implications for Type Ia Supernova Nucleosynthesis from an Experimentally Constrained $^{16}$ O $(p, α)^{13}$ N Reaction Rate

M. Alruwaili, C. Fougeres, A. M. Laird +13

The $^{16}$ O $(p, α)^{13}$ N reaction plays a key role in shaping the $α$ -particle abundance during explosive oxygen burning in Type Ia supernovae. By enhancing $α$ -production, this r…

Enhanced Nuclear Binding Near the Proton Dripline Opens Possible Bypass of the $^{64} Ge$ rp-process Waiting Point

Z. Meisel, W. -J. Ong, J. S. Randhawa

We performed astrophysics model calculations with updated nuclear data to identify a possible bypass of the $^{64} Ge$ waiting-point, a defining feature of the rapid-proton ca…

First measurement of 87Rb(α, xn) cross sections at weak r-process energies in supernova ν-driven ejecta to investigate elemental abundances in low-metallicity stars

C. Fougères, M. L. Avila, A. Psaltis +18

Observed abundances of Z ~ 40 elements in metal-poor stars vary from star to star, indicating that the rapid and slow neutron capture processes may not contribute alone to the synt…
