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 ...

A Photometric Study of Near-Contact Binary ZZ Aur [PDF]
Journal of Astronomy and Space Sciences, 2002 The BVR CCD full light curves of ZZ Aur were obtained as one of the near-contact binary observing programs at the Sobaek Mt. Observatory during Feb. 2000 - Feb. 2001. From the present observations, three primary and seven secondary times of minimum light

TV UMi: A Shallowly Eclipsing Marginal-Contact Binary
GalaxiesUsing twenty sectors of TESS observations and the hitherto unutilized radial velocities from the David Dunlap Observatory survey, we fully characterize the close binary TV UMi.

Composite contact of binary lipid membranes
The European Physical Journal E, 2013 Upon adhesion, binary lipid membranes may retain their structural identity but they may also undergo partial fusion promoted by microscopic phase separation of the components. In membranes composed of cylindrical and inverted conical lipids, a partially fused contact zone may consist of inverted micelles sandwiched between two monolayers.

Photoelectric Observations and Analysis of the Contact Binary W UMa [PDF]
Journal of Astronomy and Space Sciences, 2001 The unpublished photoelectric observations of the contact binary W UMa in ultraviolet, blue, and yellow bandpasses made on four nights during the observing seasons from April, 1984 to May, 1985 were presented.

Mass-ratio distribution of contact binary stars [PDF]
, 2023 When the mass ratio of a contact binary system drops below the critical value $q_\mathrm{min}$, the binary undergoes the tidal Darwin instability, leading to a rapid merger and observable brightening.

Astronomy & Astrophysics, 2023 Context. Among massive stars, binary interaction is the rule rather than the exception. The closest binaries – those with periods of less than ∼10 days – undergo mass transfer during core-hydrogen burning, with many of them experiencing a nuclear-timescale contact phase.

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.
