O'Connell Effect Target List
The O’Connell effect is a phenomenon found in eclipsing binaries where the maxima between eclipses are not equally bright. It was first described by Roberts (1906), codified by O’Connell (1951), and named the O’Connell effect by Milone (1968). Despite being known for over a century, however, the physical processes underlying the O’Connell effect are still shrouded in mystery.
