Differential corrections analysis of the UBVRI observations of AG phoenicis

The first photoelectric analysis of the Algol-like system AG Phe based on U, B, V, R and I light curves and modeled using the Wilson and Devinney approach, is presented. The light curves are defined by 9246 individual observations. The components and the orbit appears to be stable. The primary, more...
