LOCATION: MWF, 12:00 - 13:00, Hennings 202

AIM: 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.

LEVEL: Second year undergraduate. No prior astronomy knowledge assumed
TEXTBOOK (Required): - Foundations of Astrophysics (Ryden and Peterson)
HOURS PER WEEK: Three hours of classroom instruction per week.

Homework Guidelines, for ASTR 200

- You may work with other students when figuring out how to approach/solve the problems, but you will then INDEPENDENTLY write up your exposition of the solution for each problem.

- The clarity and logic and quality of explanation of your solution is part of the grade. Handing in confusing and/or rough work will result in full marks not being awarded. The graders have the authority to decide if a proposed solution to a problem does not sufficiently explain how and why an answer has been reached.
