Lecture 36

The s-Process

• basic physics
• path on the chart of the nuclides
• encoding in solar abundances
• searching for a site: characteristic scales
• context: post-main-sequence stellar evolution
• identifying the site: S-stars
• the crown jewel (cf chart of the nuclides)

The r-Process

• presence in solar matter
  separating r and s
• basic physics
  encoding in solar abundances
• characteristic scales
• astrophysical sites
• r-rich halo stars and universality(?)
