ASTRONOMY (AY)

Office: 206 Gallalee Hall

A student must take both AY 101 and AY 102 in order to use either of these courses to satisfy part of the N requirement of the University Core Curriculum. The lecture/laboratory courses AY 101:102 and AY 203:204 may be used to satisfy the N requirement.

AY 101 Introduction to Astronomy. 3 hours.

History of astronomy, the solar system, stars, galaxies, and the universe; recent discoveries about pulsars, black holes, and quasars will be discussed. NOTE: If the student plans to apply AY 101 toward satisfaction of the N requirement of the University Core Curriculum, AY 102 must also be taken.

AY 102 Introduction to Astronomy Laboratory. 1 hour.
Prerequisite or corequisite: AY 101.

Observation of the sun, moon, and daytime astronomical activity. Indoor exercises include stellar spectra, H-R diagram, celestial sphere, and astronomical photographic analysis. NOTE: If the student plans to apply AY 102 toward satisfaction of the N requirement of the University Core Curriculum, AY 101 must also be taken.

AY 203 Observational Astronomy. 2 hours.
Prerequisite: MATH 113 or MATH 115 (or equivalent) with a grade of “C-“ or higher.
Corequisite: AY 204 or AY 206 or permission of the instructor.

Students learn to observe and photograph planets, stars, and galaxies using several kinds of telescopes. On cloudy nights, astronomical photographs and material obtained at other observatories are studied. One lecture and one laboratory. NOTE: If the student plans to apply AY 203 toward satisfaction of the N requirement of the University Core Curriculum, AY 204 must also be taken.

AY 204 Solar System Astronomy. 3 hours.
Prerequisite: MATH 113 or MATH 115 or equivalent.
