Author: Dr. V. Perdelwitz Title: The hunt for Planet 9 Abstract: Since Batygin & Brown (2016) predicted the existence of a large ninth planet in our solar system with a semi-major axis of 700 AU, multiple groups have started efforts to detect it. We have developed a new approach to search for the planet in archival data, both via direct detection and occultations. This is the first algorithm of this kind which is able to handle large quantities of data (> 1TB) spanning multiple years.
