Current work
FGOC: Focal-Geometry and Curvature Classifier — ultra-lightweight sub-millisecond diagnostic for 2–5 point short arcs
Designed for LSST Prompt Processing, MOPS integration, and early anomaly detection
Deterministic classifier operating directly on RA/DEC/MJD (no orbit fitting or sampling)
Preprint (Zenodo DOI)
Real-Time Identification of Interstellar Objects with a Focal-Geometry Orbital Classifier for the LSST Era
https://doi.org/10.5281/zenodo.17765743
A real-time geometric–curvature framework for early identification of interstellar and non-Keplerian trajectories from 2–5 point LSST short-arc astrometry.
Compatible with LSST Prompt Processing and MOPS workflows; requires no orbit fitting, no sampling, and provides an early anomaly/ISO flag.
This preprint corresponds to the manuscript submitted to the AAS journals (AAS71533).
