YOLDAş, E.. Chromospheric activity nature of KIC 6044064. Rev. mex. astron. astrofis [online]. 2021, vol.57, n.2, pp.351-361. Epub 15-Feb-2022. ISSN 0185-1101. https://doi.org/10.22201/ia.01851101p.2021.57.02.08.
This study presents results obtained from the data of KIC 6044064 (KOI 6652). KIC 6044064 was observed by the Kepler Mission for a total of 1384.254 days. 525 minima times were determined, 264 of which were primary minima and the rest were secondary minima. The OPEA model was derived and its parameters were obtained. On the secondary component, there are two different spot bands latitudinally outstretched, consisting of three spots located with a phase interval of 0.33. The average migration period was found to be 623.063±4.870 days (1.71 ± 0.01 years) for the first spot group, while it was 1125.514 ± 7.305 days (3.08 ± 0.02 years) for the second group. The spectral types of the components seem to be G7V + K9V. Their masses and radii were determined to be and for the primary component and and for the secondary component.
