Last week was the American Astronomical Society‘s DDA sub-meeting. The DDA (Division on Dynamical Astronomy) covered “particles” (discrete objects, from dust all the way up to individual stars) as they behave under physical laws (mostly gravity, but also impacts, etc.) No shortage of computer simulations. The sub-group met in Atlanta, GA (on Georgia Tech‘s campus) May 19-23. The program:
Asteroids & Impacts
Stanley Dermott (presented by Apostolos Christou) Random walk transport of small asteroids from the Main Belt to the inner solar system
Apostolos Christou New asteroid families among the Martian Trojans
Rachel Cueva Semisecular Nodal Resonances within Binary Near-Earth Asteroid Dynamical Evolution
Rogerio Deienno Chondrite Parent Bodies as Escaped Satellites of Proto-Planetary Embryos
From Jupiter to the Oort Cloud
Rosemary Pike DO: Discovery of a 10:1 Resonator with a Novel Libration State
Luke Dones A Spiral Structure in the Inner Oort Cloud
Dynamics of TNOs
Sihao Cheng Announcement: Discovery of a Large TNO on an Extremely Wide Orbit
Yukun Huang (zoom) Retrograde TNOs from Binary Disruptions by Neptune
Ra Machado (zoom) On the cohesion of the TNO Arrokoth across different density ranges
