Photometric Analysis of Southern Contact Binary Stars II: NW Aps, BV 996 and BV 435
Abstract
An analysis of the V band light curves using the Wilson-Devinney code for NW Aps, BV 996 and BV 435 is provided. NW Aps and BV 996 have among the lowest mass ratios known and are of A-type while BV 435 has a large mass ratio of 2.185 and is the W-Type. A review of the astrophysical quantities suggests that the systems generally demonstrate properties typical of their subtypes.
