Stellar occultation campaigns on Gaia binary candidates produced 33 multi-positive events for 24 asteroids, with four showing binary or contact-binary signatures.
Collisional and dynamical models indicate the Eulalia parent body disruption ~800 Ma near the J3:1 resonance produced an impact shower that accounts for observed lunar craters formed near that time.
Derived reliable rotation periods for 96 asteroids (84 new) from 2018 KMTNet data in one square degree field, projecting >5500 periods from full ~12 deg² dataset.
