ASTR 111(F) Introduction to Astrophysics
A survey of some of the main ideas in modern astrophysics, with an emphasis on the observed properties and evolution of stars, this course is the first in the Astrophysics and Astronomy major sequences. It is also appropriate for students planning to major in one of the other sciences or mathematics, and for others who would like a quantitative introduction that emphasizes the relationship of contemporary physics to astronomy. Topics include astronomical instrumentation, radiation laws and stellar spectra, physical characteristics of the Sun and other stars, stellar formation and evolution, nucleosynthesis, white dwarfs, pulsars and neutron stars, and black holes. Some students will take this course concurrently with Physics 131 or 141. Students who take this course after having taken Physics 142 or 144 will have the opportunity to carry out more advanced assignments or projects. Evening observing sessions include use of the 24" and other telescopes to observe stars, nebulae, planets and galaxies; daytime observation of the Sun will also be possible. In addition, students will have the opportunity to learn the constellations and to find their way around the sky and to explore astronomy on the World Wide Web. Course format: lectures, three hours a week; laboratory and observing sessions. Evaluation will be based on problem sets, two hour tests, a final exam, lab reports, and observing portfolio. Prerequisites: a year of high school physics or college physics taken concurrently, or permission of the instructor. In addition, students taking Astronomy 111 must have had or be taking Mathematics 103 or equivalent.
