Two Ultralow-mass-ratio Binary Systems at Critical Evolutionary Stages
The Astronomical JournalIn this paper, we present photometric observations and period analysis of two totally eclipsing binaries with extremely low-amplitude light curves. Both binaries exhibit typical W Ursae Majoris-type light curves with total eclipses, allowing for the ...

A Possible Explanation of W-type Phenomena in V694 Peg
The Astrophysical JournalThree sets of complete multicolor light curves of V694 Peg observed in 2013, 2015, and 2019 were presented and analyzed. Our photometric solutions show that this system was an A-type shallow contact binary in 2013 and 2015 while it converted to a W-type ...

A Application of WD Model to EB Type Contact Binary System [PDF]
Journal of Astronomy and Space Sciences, 2000 The EB type contact binaries show large temperature difference ( T 1,000K) between two components. Thus we have modified the mode 3 of the WD program to adjust albedos, limb darkening coefficients and gravity darkening exponents for both components of ...
