## Summary

In their paper titled "Single Transit Detection In Kepler With Machine Learning And Onboard Spacecraft Diagnostics," authors Matthew T. Hansen and Jason A. Dittmann address the challenge of discovering exoplanets with long orbital periods using a novel technique that combines Convolutional Neural Networks (CNNs) and onboard spacecraft diagnostics from the Kepler mission. This approach allows for the identification of individual transits within a light curve, enabling the detection of planets even without additional information about the system. The developed pipeline is capable of recovering transit locations and determining orbital periods up to 800 days with high sensitivity, showing promise in uncovering new planets within the $\eta$-Earth regime. The first candidate discovered through this pipeline is KOI 1271.02, which exhibits strong Transit Timing Variations (TTVs). By jointly modeling TTVs and transits of both planets in this system, the authors aim to constrain its orbital configuration and planetary parameters. While more data is needed to fully understand KOI 1271.02, preliminary estimates suggest a radius of 5.32 $\pm$ 0.20 $R_{\oplus}$ and a mass of $28.94^{+0.23}_{-0.47}$ $M_{\oplus}$. Further investigations into this intriguing planetary system will require measuring additional TTVs for KOI 1271.01 or observing a second transit of KOI 1271.02.
