DESCRIPTION: Introductory
Course for Science Majors.
This course is an introduction to the fundamental concepts of stellar
astrophysics. In stars, gravitational forces compress the gas to
high pressures and temperatures, to the point where atomic nuclei
overcome their electrostatic repulsion and fuse together, releasing
nuclear energy and powering stellar light as we see it. In this
course, we will introduce important concepts of Newtonian mechanics,
thermodynamics, quantum mechanics, nuclear physics and relativity. We
will use this knowledge to develop a quantitative understanding of the
structure and the evolution of stars. This will allow us to interpret a
large body of observations collected by generations of astronomers, up
to this day.
TOPICS:
- Introductory mechanics, thermodynamics, quantum mechanics,
nuclear physics and relativity
- Masses, distances, temperatures and colors of stars
- The structure of stars (including the Sun)
- The birth, life and death of stars (including supernovae)
- The remnants of stars: white dwarfs, neutron stars and
black holes
PREREQUISITES:
A
working knowledge of calculus. Co-requisite: a
course in calculus-based general physics.
TEXTBOOK:
"An Introduction to Modern Astrophysics, " by
Carroll & Ostlie.
- See http://departments.weber.edu/astrophysics/Index.html
for extras from the book, such as computer codes, downloadable figures
and useful astronomy links.
- Note that the second half of the book deals with galaxies and
cosmology, and may be useful to you if you plan on taking Astro C2002.
It is also recomended that you take a look at "The Physical
Universe, " by Shu.
PROBLEM SETS:
Handed out in class and posted on
this website, approximately every other week (total of 5-6). Due one
week
later.
Policy on collaboration: You are welcome to discuss the
problems with fellow students, but you must write your own solutions,
individually.
Policy on late problem set returns: In
order to be fair to those who turn assignments in on time, points will
be deducted on assignments turned in late.
GRADING:
Problem
sets: 30%
Midterm exam: 30%
Final exam: 40%
