The Major Themes of Astrophysics

An overview...Astronomy and some of the themes of this course...

The basic understanding of stars and stellar evolution constitutes the core of modern astrophysics. In Astronomy 200 we looked at

Topic Reference in Text (by chapter)
the birth of stars chp 9,10,11
relationship between mass and luminosity chp 9
stellar classification and the HR-diagram chp 9
evolution of stars chp 12
death of stars chp 13

nucleosynthetic enrichment of the universe

chp 13

In the following lectures we will use our knowledge to consider the structure of our immediate stellar neighbourhood, our galaxy and other galaxies. We will address questions of origins:

This will bring us to some very interesting cross-roads between faith and science and we will take the opportunity to consider the interaction between our religious stance and the world views implicit in science.

But I didn't take astronomy last term!

Don't panic! We will spend the first few classes reviewing essential ideas and some of the afternoon lab exercises will help do this as well. However, you should be prepared to do a little "catch-up" reading. In particular you should review the following:

  1. Some of the basic units and measures used in astronomy:
  1. The nature of light (chp 6,7)
  2. How a star (the sun) "works (chp 7,8,9)
  3. Spectral Classes
  4. The HR Diagram

Do the catch-up reading on a "need-to-know" basis and PLEASE don't be afraid to drop by my office to discuss concepts or ideas that you may be confused about.
