- γ Dor: A pulsating component of KIC 8043961 in a stellar triple system C. Kamil H. A. Dal O. Özdarcan E. Yoldaş Física, Astronomía y Matemáticas KIC 8043961 methods: data analysis stars: individual: Dor Techniques: photometric tars: binaries:eclipsing We present new findings about KIC 8043961. We find the effective temperatures of the components as 6900±200 K for the primary, and 6598±200 K for the secondary, while the logarithm of the surface gravities are found to be 4.06 cm s−2 and 3.77 cm s−2, respectively. Combination of the light curve with the spectroscopic orbit model results leads to a mass ratio of 1.09 ± 0.07 with an orbital inclination of 73.71±0.14 and a semi-major axis of 8.05±0.22 R⊙. Masses of the primary and secondary components are calculated as 1.379±0.109 M⊙ and 1.513±0.181 M⊙, while the radii are found to be 1.806±0.084 R⊙ and 2.611±0.059 R⊙. In addition, we obtain a considerable light contribution (≈0.54%) of a third body. We compute a possible mass for the third body as 0.778±0.002 M⊙. We find that the primary component exhibits γ Dor type pulsations with 137 frequencies. 2020 artículo científico 0185-1101 https://www.redalyc.org/articulo.oa?id=57171663001 https://www.redalyc.org/journal/571/57171663001/ https://www.redalyc.org/journal/571/57171663001/html/ https://www.redalyc.org/journal/571/57171663001/57171663001.epub https://www.redalyc.org/journal/571/57171663001/movil 10.22201/ia.01851101p.2020.56.02.01 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
