Lecture 15 Explosive Nucleosynthesis and the r-Process

Lecture 15 Explosive Nucleosynthesis and the r-Process. As the shock wave passes through the star, matter is briefly heated to temperatures far above what it would have experienced in hydrostatic equilibrium. This material expands, then cools nearly adiabatically
