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…

The Critical Mass Ratio for W UMa-type Contact Binary Systems

Bojan Arbutina, Surjit Wadhwa

Contact binaries are close binary systems in which both components fill their inner Roche lobes so that the stars are in direct contact and in potential mass and energy exchange. T…

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 Six Extreme Low Mass Ratio Contact Binary Systems

Surjit S. Wadhwa, Bojan Arbutina, Jelena Petrovic +4

Multi-band (B, V and R) photometric and spectroscopic observations of six poorly studied contact binaries carried out at the Western Sydney University and Las Cumbres Observatory w…
