Astronomical research in the Department is mainly in the area of binary stars. Binary stars with orbits seen nearly edge-on undergo periodic eclipses as one star passes in front of the other. These eclipsing binaries typically have orbital periods of a few days. By studying the brightness as a function of time during eclipses, and obtaining spectra to measure radial velocities by using the Doppler effect, one can determine accurate values of stellar masses, radii, and luminosities. These data are important for testing our models that describe how stars change as they age. The Department's Droke Observatory is availabe to students doing research in this area.

The Department offers introductory and advanced courses in astronomy to undergraduate and graduate students. These include Survey of the Universe, Solar System Astronomy, Stellar Systems Astronomy, Astrophysics, and Observational Astronomy. Students with an interest in astronomy are encouraged to pursue observational projects using our facilities.
