Detection of Contact Binary Candidates Observed By TESS Using the Autoencoder Neural Network
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 ...

Spectroscopic and Photometric Study of the Contact Binary BO CVn
, 2012 We present the results of the study of the contact binary system BO CVn. We have obtained physical parameters of the components based on combined analysis of new, multi-color light curves and spectroscopic mass ratio.

A Period Study of the Near Contact Binary EG Cep [PDF]
Journal of Astronomy and Space Sciences, 2006 New eight times of minimum light of the near-contact binary EG Cep were presented. All times of minimum light for EG Cep, including ours, were collected and analyzed to study it's orbital period variation. It was found that the orbital period have varied

New Photometric Investigation of the Solar-Type Shallow-Contact Binary HH Bootis
Advances in Astronomy, 2019 The short-period solar-type contact binary HH Boo was monitored photometrically for about 8 years. It is found that the CCD light curves in the B, V, R, and I bands obtained in 2010 are symmetric, while the multicolor light curves observed in 2011 and ...

The structure equations of contact binaries [PDF]
Astronomy & Astrophysics, 2002 The structure equations of contact binaries are discussed. An equation for the transfer of mass between the com- ponents is derived. Serious uncertainties concern only the transfer of energy. They are expressed as unknown functions. An evolution code for contact binaries is presented.

Colors of Trans-Neptunian Contact Binaries [PDF]
The Astronomical Journal, 2019 Abstract The g′r′i′ colors of seven likely and potential contact binaries in the Kuiper Belt were acquired with the Magellan-Baade telescope and combined with colors from the literature to understand contact binary surfaces. The likely and potential contact binaries discovered in the dynamically cold classical population display very red/
