YOLDAş, E.  e  DAL, H. A.. The challenges of modelling the activities occurring on eclipsing binaries V1130 Cyg and V461 Lyr. Rev. mex. astron. astrofis [online]. 2021, vol.57, n.2, pp.335-349.  Epub 15-Fev-2022. ISSN 0185-1101.

We present the findings for the magnetic activities seen on V1130 Cyg and V461 Lyr. In the case of V1130 Cyg, the secondary component’s temperature was found to be 3891±50 K, while the mass ratio was computed as 0.689±0.001, and the orbital inclination as 90◦.00±0◦.01. The temperature of V461 Lyr’s secondary component was found to be 4206±50 K, and the mass ratio was calculated as 0.999±0.001 with 89◦.58±0◦.01 of orbital inclination. The analyses exhibit the effects of the stellar spots on the light curves. The models indicate that there are two types of flares in the case of V1130 Cyg, and three types of flares for V461 Lyr. The Plateau parameters have been found as 2.1997 s for Group 1 and 1.0068 s for Group 2 in the case of V1130 Lyr. They have been computed as 1.9015 s for Group 1, 2.7943 s for Group 2, and 3.4324 s for Group 3 of V461 Lyr.
