The Solar System Notification Alert Processing System (SNAPS)

A comprehensive understanding of our Solar System can be derived from the properties of asteroids, which are dynamical and physical tracers of the formation and evolution of our planetary system. Large-scale surveys provide dramatic power through understanding global trends as well as identifying and characterizing objects with unusually rare properties. Two such surveys are the ongoing Zwicky Transient Facility and the forthcoming Legacy Survey of Space and Time (LSST). These surveys do/will broadcast alerts for each moving object that is detected, providing a number of measured quantities. We have designed and constructed the Solar System Notification Alert Processing System (SNAPS; Trilling et al. 2023) to ingest these alerts and derive a number of properties for the observed asteroids. In this presentation we will present SNAPShot2, our second data release, which includes derived properties for around 100,000 asteroids. We will also briefly summarize recent work from our team on population outlier detection, on debiasing derived period solutions, and on the impact of different LSST cadences on our ability to derive asteroid properties. We will present new results of a debiased period and amplitude distribution for main belt asteroids. Finally, we will briefly describe future SNAPS milestones as we approach the delivery of LSST data in 2024/2025. This work is supported in part by the Arizona Board of Regents and NSF grant 2206796.
