Low Mass Contact Binaries: Orbital Stability at Extreme Low Mass Ratios
Surjit S. Wadhwa, Natalia R. Landin, Bojan Arbutina +5
With the ever-increasing number of light curve solutions of contact binary systems increasing number of potential bright red nova progenitors are being reported. There remains, how…
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…
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…
