Kuiper Belt Objects, Stellar Occultations

Scientific paper

The results of a search for km-sized Kuiper Belt Objects (KBOs) with the method of serendipitous stellar occultations are reported. Photometric time-series were obtained at the Dominion Astrophysical Observatory (DAO) in Victoria, British Columbia, and were analyzed for the presence of occultation events. Observations were performed at 40 Hz and included a total of 5.0 star-hours for target stars in the ecliptic open cluster M35, and 2.1 star-hours for control stars in the off-ecliptic open cluster M34. To evaluate the recovery fraction of the analysis method, and thereby determine the limiting detectable size, artificial occultation events were added to the data. No viable candidate occultation events were detected. This limits the cumulative surface density of KBOs to 3.5 × 10 10 deg -2 (95% confidence) for KBOs brighter than m R =35.3 (larger than ~860m in diameter, assuming a geometric albedo of 0.04 and a distance of 40 AU). To evaluate false-positive rates, a method of simulating scintillation effects was developed.
