Photometric observations of primary minimum inU, B, andV filters have been discussed. The amplitude of variation in all the three filters is 0m.66. We do not find variations in the period and its revised value is 1d.0047115.

AB Andromedae – An overcontact eclipsing binary
New Astronomy, 2021Abstract In an effort to resolve the discrepancy between two earlier studies, new radial velocity and photometric data have been obtained and analyzed by Roche modelling for AB Andromedae, an overcontact W-subtype eclipsing binary. The new values for the basic data, m1 = 0.60 (3) Mʘ, m2 = 1.14 (3) Mʘ, R1 = 0.81 (1) Rʘ, R2 = 1.08 (1) Rʘ, L1 = 0.73 (6)

Eclipsing Binaries (1928-1929)
2021The run of events that led to the practical discovery by Hubble and Humason of universal expansion began with the publication of the first of Albert Einstein’s theoretical papers on relativity in the early part of the 20th century. As seminal works go, you couldn’t do much better than his twin masterpieces, the second of which was conceived and refined

Publications of the Astronomical Society of the Pacific, 1956
The observations reported here were obtained in the course of a program of searching for eclipsing binaries which may increase our meager knowledge of the fundamental properties of stars not on the main sequence. Of the stars discussed, three (V694 Aquilae, UU Cancri, and GG Cassiopeiae), while of considerable interest, do not appear promising from ...

Close Binary Eclipsing Systems
2003Within the GCVS you will find over 6000 eclipsing binary variable stars. The Algol-type eclipsing binary stars are the most numerous; however, over one thousand eclipsing stars have not been well studied and as a result have not been categorized within the three major groups (i.e. EA, EB, or EW).
