Eclipse Depth Variations in Seven Eclipsing Binaries as Observed by KELT and TESS
The Astronomical JournalA set of eclipsing binary systems exhibit a changing inclination over time due to the gravitational influence of a third stellar companion. These changing inclinations manifest in photometric observations over time as eclipse depth variations.

Contact-binary Evolution with Energy Transfer and Saturated Magnetic Braking
The Astrophysical JournalThe evolution of low-mass contact binaries is influenced by angular momentum loss, mass and energy transfer (ET), and the nuclear evolution of the components.

Detection of Semidetached Eclipsing Binaries from TESS
The Astronomical JournalSemidetached binaries, distinguished by their mass transfer phase, play a crucial role in elucidating the physics of mass transfer within interacting binary systems.

Proceedings of the International Astronomical Union, 2006 Only a handful of binary central stars of planetary nebulae (PNe) are known today, due to the difficulty of detecting their companions. Preliminary results from radial velocity surveys, however, seem to indicate that binarity plays a fundamental, rather than marginal role in the evolution of PNe and that the close binary fraction might be much larger ...

The Astrophysical Journal Supplement SeriesWe utilize a hybrid approach that integrates the traditional cross-correlation function (CCF) and machine learning to detect spectroscopic multiple star systems, specifically focusing on double-line spectroscopic binaries (SB2s).

Symposium - International Astronomical Union, 1992 This paper briefly reviews the physical properties of symbiotic stars: long-period interacting binaries composed of a red giant primary star and a hot companion. Two types of binaries produce symbiotic optical spectra: semi-detached systems with a main sequence secondary and detached systems with a white dwarf secondary.

CN Trianguli: A W-type Contact Binary Exhibiting A-type Light Curve via Starspot-induced Dimming
The Astrophysical JournalWe present comprehensive photometric observations and analysis of the totally eclipsing binary CN Tri. The photometric solutions suggest it as an extremely low mass ratio contact binary system with q ∼ 0.08.
