Courses taught by William F. van Altena
The following are courses that I normally teach along with a rough syllabus for the last time that I taught them.
Astronomy 110 - Birth, Life, and Death of Stars
Astronomy 250 - Observational Astronomy
Astronomy 355 - Observational Astonomy (Advanced)
Astronomy 575 - Astrometry
Astronomy 701 - Research Seminar in Astrometry
Return to van Altena Homepage
This course in is intended for non-science majors. An introduction to the solar system and stars, the physical principles involved in understanding their origin and evolution, and to the instruments of astronomy used to observe them. I will be teaching this course in the Spring term of 2001.
This course was taught through the academic year 1998/99. It has now been replaced by a lower level course, Astro 205, which concentrates on the hands-on use of our new Campus telescope using electronic detectors and understanding the reduction of astronomical data using computers. More advanced students now take Astro 355, which concentrates on the design and use of optical telescopes, photometers, spectrographs, and detectors to make astronomical observations. An emphasis is placed on the understanding of geometrical optics and techniques of ray tracing in the design of astronomical instruiments and telescopes.

Astronomy 701 - Research Seminar in Astrometry
This research seminar brings together individuals in the Astronomy Department who are working on a variety of astrometric problems on a weekly basis. The goal of the seminar is to familiarize the participants with current research activities in astrometry and aid in the solution of problems that each individual might be having. This course normally meets once a week throughout each academic year.
