Searching for Kuiper Belt Objects

This study focuses on the search for Kuiper Belt Objects (KBOs), which are rocky and icy bodies located approximately 30-50 AU from the Sun. As remnants from the era of planet formation, around 1,000 KBOs have been identified, with only a few dozen observed beyond an R magnitude of 24. Utilizing a 6.5-meter telescope equipped with a 36 CCD mosaic camera (MEGACAM), we explore optimal methods for identifying multiple KBOs within a single observation. This research is supported by a team of mentors and funding from NASA and the Arizona Space Grant Consortium.

  1. Searching for Kuiper Belt Objects Deborah L. Hamm Mentors David Trilling, Cesar Fuentes, Michael Mommert, Paulo Penteado

  2. Kuiper Belt Objects (KBOs) • Rocky, icy bodies • Located ~ 30-50 AU • Remnants of the era of planet formation • ~1000 known • Only a few tens @ R > 24

  3. Instruments / Data • 6.5 meter telescopes • 36 CCD mosaic camera MEGACAM • 36 Fields • R magnitude limiting depth of ~25.2

  4. MEGACAM Mosaic 36 CCDs 9 X 4 array FOV: 24’ X 24’ .16 deg2 FOV (1 CCD): 160’’ X 360’’ Gaps ~6’’

  5. Expectations • Expectations based on previous studies • 4 KBOs in a single pointing • 3-5 arcseconds/hr for a KBO @ 30 AU
