A Photometric Study of the Near-Contact Binary XZ Persei

Michaels, E. J.

Presented are two sets of multi-band CCD photometry of the Algol-type binary XZ Persei. Photometric solutions were derived using the Wilson-Devinney program for each dataset. The solution results indicate XZ Per is a semi-detached, near-contact binary whose less-massive secondary star fills its Roche lobe. Asymmetries in the light curves were mode…

A Photometric Study of the Eclipsing Binary QT Ursae Majoris

Michaels, E. J.

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 …
