Charged-particle branching ratios above the neutron threshold in ${}^{19}$F: constraining ${}^{15}$N production in core-collapse supernovae

P. Adsley, F. Hammache, N. de Séréville +28

Spatially-correlated overabundances of ${}^{15}$N and ${}^{18}$O observed in some low-density graphite meteoritic grains have been connected to nucleosynthesis taking place in the heli…
