V717 Andromedae: An Active Low Mass Ratio Contact Binary
S. S. Wadhwa, M. Grozdanovic, N. F. H. Tothill +2
Multi-band photometric analysis of the contact binary V717 Andromedae (V717 And) is presented. The system is found to be an extreme low mass ratio system (q = 0.197) with high incl…

Photometric and Spectroscopic study of Ten Low Mass Ratio Contact Binary Systems: Orbital Stability, O'Connell Effect and Infra-red Calcium Line Filling
Surjit S. Wadhwa, Adam Popowicz, Raul Michel +5
Low mass ratio contact binary systems are more likely to have unstable orbits and potentially merge. In addition, such systems exhibit characteristics such as starspots and high en…
