Effects of Metallicity on the Instability Mass Ratio of Low Mass Contact Binary Systems

Surjit S. Wadhwa, Natalia R. Landin, Petar Kostic +7

The orbital stability of contact binary systems has been receiving considerable attention recently. Theoretical studies indicate that merger is likely to occur at very low mass rat…

Effective Temperature and the Light Curve Solution of Contact Binary Systems

Surjit Wadhwa, Nick Tothill, Miroslav Filipovic +1

With increasing number of contact binary discoveries and the recognition that luminous red novae are the result of contact binary merger events, there has been a significant increa…

Photometric and Spectroscopic Study of Two Low Mass Ratio Contact Binary Systems: CRTS J225828.7-121122 and CRTS J030053.5+230139

Surjit S. Wadhwa, Jelena Petrovic, Nick F. H. Tothill +3

The study reports photometric and spectroscopic observations of two recently recognised contact binary systems. Both systems show total eclipses and analysis of the light curves in…

A Study of Twelve Potential Merger Candidate Contact Binary Systems

Surjit S. Wadhwa, Bojan Arbutina, Nick F. H. Tothill +4

Photometric observations and analysis of twelve previously poorly studied contact binary systems is presented. All show total eclipses and have extremely low mass ratios ranging fr…
