[76.18] UBV Photometry, Times of Minimum, and Light Curve Solutions for the Algol system, YY Cet

V Ponce (UVa), R Williamon (Fernbank), J Sowell (GA Tech)

YY Cet is an Algol system with partial eclipses and a period of 19 hours. The components appear to be slightly evolved A/F and G/K stars. UBV photometry has been acquired over four seasons with the 36-inch telescope at the DeKalb County (GA) School System's Fernbank Science Center. Times of minimum have been determined per filter and season, and a literature search has provided additional values for examining the possibility of period changes. Preliminary light curve solutions using all of our data have been derived with the Wilson-Devinney binary star code.
