| contents | Four new γ Doradus variables in eclipsing binaries: revised pulsation period relations O. Özdarcan Ö. Çakirli Física, Astronomía y Matemáticas stars Binaries eclipsing individual KIC 2720354 We present photometric light curve modelling of four Kepler eclipsing binaries KIC2720354, KIC10063044, KIC11724091 and KIC8565912. The modelling results show that KIC10063044 is a semi-detached eclipsing binary, while the other systems are detached eclipsing binaries. Estimated physical parameters of these systems and residuals from the best-fitting light curve models strongly indicate γ Dor type pulsations on the primary components of the target systems. Evaluating the relations between pulsation period (Ppuls) and orbital period (Porb), the force exerted to per gram on the surface of the pulsating star (F/Mpuls) and the fractional radius of the pulsating star (r), we find that linear relations on a logarithmic scale still exist, but with a smaller slope than reported in previous studies. 2020 artículo científico 0185-1101 https://www.redalyc.org/articulo.oa?id=57171663012 https://www.redalyc.org/journal/571/57171663012/ https://www.redalyc.org/journal/571/57171663012/html/ https://www.redalyc.org/journal/571/57171663012/57171663012.epub https://www.redalyc.org/journal/571/57171663012/movil 10.22201/ia.01851101p.2020.56.02.12 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.2 Vol.56 |
