ASTR 496 class schedule data for spring 2025
	CRN	Type	Section	Time	Day	Location	Instructor	Section Details
	41452	Lecture	NPA	10:00AM -10:50AM	MWF	134 Astronomy Building	Fields, B	Part of Term: 1 Date Range: 01/21/25-05/07/25 Credit: 3 hours Section Title: Nuclear & Particle Astrophysic Section Info: NPA: Nuclear and Particle Astrophysics. This course is targeted to advanced undergraduate students, with no nuclear or particle physics prerequisites. Need instructors approval. We will develop and apply basic nuclear and particle physics to trace highlights in the history of cosmic matter from the big bang to the present, using all available cosmic messengers. Planned topics include: Early universe thermodynamics, relic particles, and dark matter. Primordial nucleosynthesis predictions, observations, implications, and future tests. Stellar burning phases and nucleosynthesis. Supernovae and explosive nucleosynthesis. Solar, geophysical, atmospheric, supernova, jet-driven, and cosmological neutrinos. Neutron capture processes: theory, astrophysical sites, and observations. Gamma-ray bursts and kilonovae. Ultra-high energy cosmic rays. Cosmic-ray nucleosynthesis and $\gamma$-ray production. The first stars. Galactic and cosmic chemical evolution. The emphasis will be on physical arguments and quantitative estimates to understand observations. ASTR 496 NPA is for undergraduate students. Graduate students should enroll in ASTR 596 NPA.
