The O’Connell Effect in the Eclipsing Binary KID11560447

Charlyn E. Ortmann
Dr. Vayujeet Gokhale, Faculty Mentor

A multitude of eclipsing binary star systems exhibit a unique phenomenon in their light curves known as the O’Connell effect (OCE). The OCE is an inequality in the out-of-phase maxima in the light curve of an eclipsing binary. In this talk, we discuss the time evolution of a particular eclipsing binary, KID 11560447, and its interesting characteristic of a varying OCE. We compare the OCE in KID 11560447 to the OCE in other eclipsing binary systems and discuss possible models to explain the origin of the O’Connell effect, as well as lay out a plan to continue these investigations in the summer by targeting Kepler-field objects using the newly installed 17-inch PlaneWave telescope at the Truman Observatory.
