The light curves were analysed using the latest version of the Wilson-Devinney code, and the obtained data were used to estimate the physical parameters of the systems. TYC 2402-643-1 and TYC 2913-2145-1, having mass ratio < 0.25, can be classified as Extreme Mass Ratio Binary (EMRBs) systems and belong to the A-subtype class of the EW. The third one, TYC 2703-1235-1, having mass ratio q about 3 (1/q = 0.33) belongs to W-subtype class of the EW. The absolute dimensions of the primaries and secondaries were estimated and investigated using different evolutionary diagrams. The parameters of the progenitors of the components of the systems were calculated and the results are consistent with the determination of the subtypes. 2022 artículo científico 0185-1101 https://www.redalyc.org/articulo.oa?id=57175492006 https://www.redalyc.org/journal/571/57175492006/ https://www.redalyc.org/journal/571/57175492006/html/ https://www.redalyc.org/journal/571/57175492006/57175492006.epub https://www.redalyc.org/journal/571/57175492006/movil 10.22201/ia.01851101p.2022.58.01.06 en http://www.redalyc.org/revista.oa?id=571 Revista Mexicana de Astronomía y Astrofísica application/pdf Universidad Nacional Autónoma de México Revista Mexicana de Astronomía y Astrofísica (México) Num.1 Vol.58 |
