[4.07U] A Light Curve of Theta-1 Orionis A

J.R. Robertson, S.C. Stutts, D.B. Caton (Appalachian State University)

Theta-1 Orionis A (V1016 Ori), a member of the Trapezium, was only discovered to be an eclipsing binary system in 1974. The study of this system has been recently summarized by Strickland and Lloyd (The Observatory, 120, 2000, pp. 141-149).

We are obtaining a complete light curve in VBRI using a CCD on the 18-inch telescope at Appalachian State University's Dark Sky Observatory. We have obtained new times of primary minimum and are searching for the undiscovered secondary eclipse as well. A status update on this project will be presented.

We gratefully acknowledge the support of the National Science Foundation, through grant AST-9731062, and the Dunham Fund for Astrophysical Research. We would also like to thank the staff of the U.S. Naval Observatory Library and acknowledge the use of the Simbad Astronomical Data Base. The instrumentation help provided by Lee Hawkins and Robert Miller is appreciated as well.
