Physics and Astronomy Colloquium

Some intriguing discoveries in neutrino physics have been made in the past decade, clarifying their behavior in vacuum and in matter, and defining their role as a component of dark matter. But a lot remains to be learned. I will describe some of the questions that impact nuclear physics, including neutrinos in quiescent and explosive massive stars, their properties under particle-antiparticle conjugation, and their importance in
a variety of mechanisms for nucleosynthesis.
