- Multicolor study of V1009 Per, a close binary system at the beginning of the overcontact phase, and of CRTS J031642.2+332639, a new binary system in the same field Raúl Michel Francesco Acerbi Carlo Barani Massimiliano Martignoni Física, Astronomía y Matemáticas stars Binaries 2+332639 eclipsing V1009 Per The first multicolor observations and light curve solutions of the eclipsing binary systems V1009 Per and CRTS J031642.2+332639 are presented. Using the 2005 version of the Wilson-Devinney code, both systems are found to be W UMa contact binaries. V1009 Per has a mass ratio of q = 0.362 ± 0.002 and a shallow fill out parameter of f = 11.8 ± 0.6% while CRTS J031642.2+332639 has a mass ratio of q = 2.507 ± 0.006 and a fill out of f = 13.6 ± 0.4%. High orbital inclinations, i = 85◦.9 for V1009 Per and i = 83◦.2 for CRTS J031642.2+332639, imply that both systems are total eclipsing binaries and that the photometric parameters here obtained are reliable. Based on 16 times of minimum the orbital period variations of V1009 Per are discussed. The absolute dimensions of the systems are estimated and, from the log M − log L diagram, it is found that both components of the systems follow the general pattern of the W subtype W Ursae Majoris systems. 2019 artículo científico 0185-1101 https://www.redalyc.org/articulo.oa?id=57171616008 https://www.redalyc.org/journal/571/57171616008/ https://www.redalyc.org/journal/571/57171616008/html/ https://www.redalyc.org/journal/571/57171616008/57171616008.epub https://www.redalyc.org/journal/571/57171616008/movil 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.55
