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…
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…
