Close binary system GO Cyg

Abstract: a b s t r a c tIn this study, we present long term photometric variations of the close binary system GO Cyg. Modelling of the system shows that the primary is filling Roche lobe and the secondary of the system is almost filling its Roche lobe. The physical parameters of the system are M 1 = 3.0 ± 0.2M , M 2 = 1.3 ± 0.1M , R 1 = 2.50 ± 0.12R , R 2 = 1.75 ± 0.09R , L 1 = 64 ± 9L , L 2 = 4.9 ± 0.7L , and a = 5.5 ± 0.3R . Our results show that GO Cyg is the most massive system near contact binary (NCB). Analysis o… Show more

“…The absolute parameters of V1191 Cyg, with their error values, obtained in this study (see Table 5) are consistent with those given by Ulaş et al (2012) and Zhu et al (2011)(see Table 6). Deb and Singh (2011), (3) Ulaş et al (2012), (4) Zhu et al (2011) V1073 Cyg: The results given in Tables 4 and 5 are obtained with the MODE 3 for overcontact binaries and one dark spot located on the cooler component of V1073 Cyg. The results given by Ahn et al (1992) on the masses, radii, temperatures, filling factor for V1073 Cyg binary system were somewhat different from the results of this study.…”

“…Based on the systematic deviation of the fit in R passband around primary minimum they pointed out a probability of the presence of a third companion. Recently, Ulaş et al (2012) presented the parameters for the hot and cooler companions together with the photometric and spectroscopic variations of V1191 Cyg binary system. This system was also studied by Zhu et al (2011) using their CCD photometric light curves in BV(RI)c bands obtained in 2009.…”
