Observational Astronomy
Course Description

This course will serve as an introduction to the tools and techniques used in optical and radio astronomy. Using the facilities at the University of Utah Observatory, we will explore the cosmos and study the Sun, planets, asteroids, stars and galaxies. Measurements of basic properties of astronomical objects will be performed. Quantitative analysis of these measurements will enable us to determine such things as the mass of jupiter as well as the ages of stars. The course will cover the following topics:

Basic Optical Observational Techniques

Finding astronomical objects.
Optical Telescope Design.
Imaging astronomical objects with a CCD camera.
Filters and Photometry.
Design and use of spectrographs.
Atmospheric effects and limitations.

Basic Concepts of Radio Astronomy

The electromagnetic spectrum.
Radio Spectra, Brightness and Temperature
Radio Detectors
Properties of Radio Sources (Sun, Jupiter, Galaxy, ET...)

Observing projects will be an integral component of the course. The facilities available will include a 7 foot diameter Radio Telescope, one 12" Optical telescope and six 8" optical telescopes. Each of the optical telescopes will be equipped with a CCD camera. A spectrograph will be available for use on the 12" telescope. Computer equipment will be available to store and analyze the images obtained from each telescope. The observing projects may include, planetary satellite orbits, asteroid photometry, Cepheid variable stars, gaseous nebulae, galactic rotation, color-magnitude diagrams for star clusters. Prerequisites: Algebra. Familiarity with computers. A background in physics would be useful. However an enthusiatic backyard astronomer without these prerequisites would be welcome.
