One method of finding exoplanets is to look for small changes in the brightness of a star that result from the planet moving across the disk of the star, forming an occultation. This article describes long-term observations of a star that showed periodic dimmings, confirming the presence of an exoplanet. The results of this article contribute to progress in the field of exoplanet study.
