A Photometric Study of the Eclipsing Binary QT Ursae Majoris.

MICHAELS E.

Abstract (from CDS):

Presented are the first multiband light curves of the eclipsing binary QT Ursae Majoris. The light curves were analyzed using the Wilson-Devinney program to find the best-fit stellar model. Asymmetries in the light curves required spots to be included in the model. The solution results give a Roche Lobe fill-out of 13%, which is consistent with a W-type contact binary. New linear and quadratic ephemerides were computed using 31 times of minima, including 8 new ones from this study.
