摘要

我们提出了在V1130Cyg和V461Lyr上看到的磁性活动的发现。在V1130Cyg的情况下，发现次级部件的温度为3891±50K，而质量比计算为0.689±0.001，轨道倾角为90°.00±0°.01。V461Lyr的次级成分的温度为4206±50K，轨道倾角为89°.58±0°.01时，质量比为0.999±0.001。这些分析显示了恒星斑点对光线曲线的影响。模型表明，在V1130Cyg的情况下有两种类型的耀斑，而在V461Lyr的情况下则有三种类型的光斑。在V1130 Lyr的情况下，第1组的Plateau参数为2.1997 s，第2组的Platiod参数为1.0068 s。它们被计算为V461Lyr第1组的1.9015秒、第2组的2.7943秒和第3组的3.4324秒。

THE CHALLENGES OF MODELLING THE ACTIVITIES OCCURRING ON ECLIPSING BINARIES V1130 CYG AND V461 LYR

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.
