This web page concerns ASTR 200 for the period :
September - December 2017.
This course is an introduction to astrophysics. In it we will look at a broad range of astronomical topics ranging from the Solar System to the most distant galaxies, and learn how astronomical phenomena are governed by physical laws and principles.
The main goals of the course are to:
- provide an overview of the Universe and its constituents, including stars, planets, galaxies, white dwarfs, neutron stars, supernovae, dark matter and black holes.
- improve your understanding of physical processes in astronomy.
- help you develop skills at applying physics and math to solve abstract and practical problems
Note: This course also serves as an introduction for ASTR 205 (Stars and Stellar Populations) which is offered in term two, and uses the same text book.
Second year undergraduate. No prior astronomy knowledge assumed; see
UBC calendar entry for PHYS and MATH pre-reqs.
TEXTBOOK (Required): - Foundations of Astrophysics (Ryden and Peterson)
HOURS PER WEEK: Three hours of classroom instruction per week.
