This is the original light curve detected by the model from Kepler's 16th quarter observation. The 16th quarter lasted approximately 80 days. Figure 1 shows the light curves that the model flagged as possible transits. Although long-term brightness fluctuations are observed, they do not seem to affect the recurrence of the signal with a period of 2.9376 days. Although the light curve shares some characteristics of the light curve of a variable star, this star has not been cataloged as a variable star7. It is possible that it is an uncataloged variable, but given the star's relative proximity to Earth (about 978 calendar years) and the degree to which it has cataloged nearby variables, this seems unlikely.

This paper reports on the detection of periodic dimming events in the light curve of the G1.5IV-V star KIC 1718360. It is based on visible-light observations made by both the TESS space telescope and the Kepler space telescope.
Analysis of the data indicates a possible orbiting object with a radius of approximately 1.048 Earth radii, a period of 2.938 days, and a semimajor axis of 0.04 AU. Initial observations were made on Kepler Quarter 16 data using the One-Class SVM machine learning method. Subsequent observations with the TESS space telescope confirmed these findings.
Although more data are still needed for validation, these results could contribute to the growing body of data on Earth-like planets with short-period orbits.
