LUMINOSITY DISCREPANCY IN THE EQUAL-MASS, PRE-MAIN-SEQUENCE ECLIPSING BINARY PAR 1802: NON-COEVALITY OR TIDAL HEATING?

Parenago 1802, a member of the ~1 Myr Orion Nebula Cluster, is a double-lined, detached eclipsing binary in a 4.674 day orbit, with equal-mass components ([M subscript 2] [over M subscript 1] = 0.985 ± 0.029). Here we present extensive VI[subscript C] JHK [subscript S] light curves (LCs) spanning ~1...
