KIC 9272276: An Extreme Low Mass Ratio Red Nova Progenitor
Surjit Wadhwa, Marko Grozdanovic, Bojan Arbutina +2
Photometric analysis of KIC 9272276 (K9272), a low-mass contact binary system, is presented. We find it to be an example of an extreme low mass ratio system that satisfies the curr…
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…
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…
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…
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…
