Prerequisite and Course Description
Astronomy 309N is an elective course for non-science majors. The only prerequisite is a one-semester college-level
introductory course in astronomy (Ast 301 or equivalent). We will explore the nature and life cycles of stars both
ordinary and exotic, and address some of the latest discoveries about these "engines of the Universe."
By the end of the semester, you should have a deeper understanding of how the Sun and other stars
create the energy that keeps them glowing; how stars are born, age, and die;
what we now know about the planets
around other stars; how stars create the elements of which the Earth and living things are made; the nature of
cosmic explosions such as supernovae; and the evidence that black holes really do exist. We will also cover
some basic ideas of the theories of relativity (in a qualitative way) and discuss what exciting discoveries might
be made in the near future about the nature of our Universe, by planned space missions and experiments.
Textbooks
Extreme Stars by James Kaler (2001) and Cosmic Catastrophes by J. Craig Wheeler
(2000). Both will be on reserve at the Undergraduate Library. Kaler's book will be used mostly in the first half
of the course, and Wheeler's in the second half. These will be supplemented by some packets of Instructor's Notes
posted on the class website, along with abbreviated versions of Power Point slides from the lectures. **Since Kaler's book
may not be
available at the UT Co-op until late January, you may wish to purchase it from another vendor or use the library
copy. **
