Binary Analysis and Period Study of the Long-period, High-mass-ratio Contact Binary KIC 7766185
The Astronomical JournalWe present an in-depth photometric and spectroscopic study of the contact binary KIC 7766185. Spectroscopic observations were conducted on the Mayall 4 m telescope at Kitt Peak National Observatory and used to extract radial velocities.

ZZ Piscis Austrinus (ZZ PsA): a bright red nova progenitor and the instability mass ratio of contact binary stars [PDF]
Monthly notices of the Royal Astronomical Society, 2020 ZZ Piscis Austrinus (ZZ PsA) is a neglected bright southern contact binary system with maximum V magnitude of 9.26. We present the first multiband photometric analysis and find the system to be in deep contact (>95 per cent) with an extremely low mass ...

Detection and Seismic Study of Gravity and Rossby Mode Pulsations in Four Contact Binaries
The Astrophysical Journal, 2023 We report the detection of gravity ( g ) and Rossby ( r ) mode pulsations of four short-period eclipsing binaries, KIC 5439790, KIC 7501230, KIC 9350889, and KIC 9453192 based on the 4 yr Kepler high-precision photometry.

From a Dinuclear System to Close Binary Cosmic Objects
Astronomy, 2023 Applying the ideas from microscopic objects to macroscopic stellar and galactic systems, the evolution of compact di-stars and di-galaxies is studied in the mass asymmetry coordinate. The formation of stable binary systems is analyzed.
