STATISTICAL SURVEY FOR THE PHYSICAL CHARACTERISTIC OF NEAR CONTACT BINARY(NCBs) [PDF]
Journal of Astronomy and Space Sciences, 2005 The absolute dimensions and orbital elements of 66 near contact binaries, collected from literatures, have been analyzed to investigate the physical characteristics of the near contact binaries as well as co-relations among physical parameters.

Detection of Contact Binary Candidates Observed By TESS Using the Autoencoder Neural Network [PDF]
The Astronomical JournalA contact binary may be the progenitor of a red nova that eventually produces a merger event and have a cut-off period of around 0.2 days. Therefore, a large number of contact binaries is needed to search for the progenitor of red novae and to study the ...

CCD Photometry of Low Mass Ratio Contact Binary FP Boo - IV [PDF]
Journal of Astronomy and Space Sciences, 2009 We present new B, V, and R CCD photometric light curves for the low mass ratio contact binary FP Boo. A new photometric solution and absolute physical dimensions of the system were derived by applying the Wilson-Devinney program to our observed light ...

LOW MASS RATIO CONTACT BINARY SYSTEMS HN UMa AND II UMa - III [PDF]
Journal of Astronomy and Space Sciences, 2006 We present newly observed BVRI CCD light curves for low mass ratio contact binaries, HN UMa and II UMa. The absolute dimensions of these objects were obtained by applying the Wilson-Devinney program to previously published spectroscopic analysis and to ...

The Strength and Shapes of Contact Binary Objects [PDF]
The Astrophysical Journal LettersWhile contact binary objects are common in the solar system, their formation mechanism is unclear. In this work we examine several contact binaries and calculate the necessary strength parameters that allow the two lobes to merge without the smaller of ...

Effects of Metallicity on the Instability Mass Ratio of Low Mass Contact Binary Systems. [PDF]
Monthly notices of the Royal Astronomical Society, 2023 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 ratios, but the actual mass ratio at which merger may take place is likely ...

The first photometric and orbital period investigation of an extremely low mass ratio contact binary with a sudden period change, TYC 4002-2628-1 [PDF]
Monthly notices of the Royal Astronomical Society, 2022 Photometric observations for the totally eclipsing binary system TYC 4002-2628-1, were obtained between November 2020 and November 2021. To determine the stellar atmospheric parameters, a spectral image was taken with the 2.16 m telescope at National ...
