Description
This lecture provides overview of recent progress in understanding of explosive nucleosynthesis of Li and heavy elements. Recent observations have revealed that nova explosions are major source of Li in the Galaxy. Observational methods and results of novae are presented. The astrophysical site of the r-process that is a major source of elements heavier than iron in the universe is a longstanding problem. The detection of gravitational wave and follow-up optical observations have identified the merger of binary neutron stars to be a site of the r-process. Spectroscopic observations of early generations of stars also give useful constraints on the nature of the r-process. Current understanding of the r-process based on observational results is reviewed.
