    Effects of Spot Occultations on Exoplanet Mid-Transit Timing Measurements
    (Türk Astronomi Derneği, 2023) Solmaz, Arif; Basturk, Ozgur; Akyüz, Aysun
    It is critical to detect timing variations in transit light curves in order to accurately determine the characteristics of transiting exoplanets. Transit and occultation timings are subject to change, mostly cyclically, by the anomalies in the light curve morphology due to limb darkening, stellar activity, ellipsoidal variations of the host star, and physical phenomenae such as additional bodies in the system, orbital precession, angular momentum change in the order of seconds, minutes, or hours. The effects of the occultations of surface spots observed in magnetically active host stars by a transiting planet on the measurements of mid-transit times are investigated in this study.
