Effects of Hoyle state de-excitation on $\nu p$-process nucleosynthesis and Galactic chemical evolution

Hirokazu Sasaki, Yuta Yamazaki, Toshitaka Kajino +1

The partcle-induced hadronic de-excitation of the Hoyle state in ${}^{12}$C induced by inelastic scattering in a hot and dense plasma can enhance the triple-alpha reaction rate. This…
