COURSE INFORMATION

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.

Homework 1. PDF format. Due Sept 22, 5 PM (see top of homework page for instruction). Homework 1 Solutions. PDF format.
      CORRECTION: The 3rd sentence of question 3(c) should read: After this burn, compute (showing your steps) the period of the first joviocentric orbit (in units of Earth days) of the spacecraft, assuming a Keplerian elliptical orbit around Jupiter.
      CLARIFICATION: 'Orbital elements' are the parameters (numbers) which describe the size, shape, and orientation of the orbital motion. The only two 'orbital elements' we have discussed are the semimajor axis (a) and the orbital eccentricity (e, that ranges from 0 to 1 and describes how non-circular the ellipse is). There are other orbital elements related to tilt and orientation (you can google), but we are not covering them in ASTR 200.

Homework 2. PDF format. Due Sept 29, 5 PM (see top of homework page for instruction).
      OPTIONAL For question 2, if you want to use an albedo, use the albedo of 0.16 listed in table 8.2.
Homework 2 Solutions. PDF format. ERRATA: In solution for 2(a) 1.2 must be squared, so correct answer is 1.45.

Homework 3. PDF format. Due Oct 6, 5 PM (see top of homework page for instruction).
      Optional, but recommended, Graph Paper Sheet. PDF format.
      CLARIFICATION: For question 2, use the nominal cloud density in text equation (17.6) of 3E-15 kg/cubic meter (the number also as used in class).
Homework 3 Solutions. PDF format. ERRATA: In 3d the solution incorrectly says the 8--4 transition (which is H_beta) is line G. It is in fact line H (as was identified in part a).

Homework 4. PDF format. Due FRIDAY Oct 21, 4 PM (see top of homework page for instruction). EXTENDED DUE DATE: Oct 24, 4:30 PM
Homework 4 Solutions. PDF format.

Homework 5. PDF format. Due WEDNESDAY Oct 26, 4 PM (see top of homework page for instruction).
Homework 5 Solutions. PDF format.

Homework 6. PDF format. Due Thursday Nov 10, 5 PM (see top of homework page for instruction).

Homework 7. PDF format. Due Thursday Nov 17, 5 PM (see top of homework page for instruction).
Homework 7 Solutions. PDF format.

Homework 8. PDF format. Due Thursday Nov 24, 5 PM (see top of homework page for instruction).
CLARIFICATIONS for Q3:
1. The 1st sentence should read "...black hole of mass M_BH would resist..."
2. When you need the properties of 'a star', just use solar values.
