(O-C) curve of the binary system KIC 06852488
Listed in IVOA Registry (Virtual Observatory)
The continuous and unbroken time-series photometry data of Kepler and the Transiting Exoplanet Survey Satellite (TESS) provide a good opportunity to study the continuous variations in the light curve of binary stars.
Description
This paper reports the discoveries of the correlation between the two maxima on the light curve of KIC06852488 and the correlation between the O'Connell effect and the O-C curve. The Max I and Max II vary with a same cycle length of ~2000days and a 180{deg} phase difference, and the variation of the Max II coincides with the O-C curve of the primary light minima.
After analyzing the Kepler and TESS light curves, it is detected that this binary is a semi-detached system with a mass ratio of 0.4622({+/-}0.0036). The secondary component is filling its critical Roche lobe, while the primary component is only filling 12.25({+/-}0.10)% of the lobe volume that contributes more than 85% luminosity of the total system. The variation of the O'Connell effect could be explained by an evolving hot spot on the primary component and an evolving cool spot on the secondary component.

It is found that their positions are symmetrical with the inner Lagrange L1 point. After subtracting the binary brightness changes, six optical flares are detected that come from the cool secondary. We calculated the energy of flares and found that all of the flares are superflares.
Both the flares and an evolving dark spot on the lobe-filling secondary component make the system a very interesting source to investigate the effects of binary interaction on the magnetic activities.
