| Abstract: | Planet Nine has been primarily proposed to explain the observed structure of the Kuiper belt objects with semi-major axes beyond 200 AU. In this talk, I will report on our multi-year observational program to search for Planet Nine with the Hyper Suprime-Cam instrument on the 8 meter Subaru telescope. Our survey area covers the sky region near the apocenters of the proposed path of Planet Nine. I will describe the challenges involved with the data reduction using the bleeding edge of the Rubin LSST pipeline, its management over computing clusters separated over multiple continents and having to deal with a large number of false positive detections in difference images. I will summarize the current best constraints on the existence of Planet Nine. |
