Predictions of the LSST Solar System (non-)Yield
Joseph Murtagh, Ian Chow
We present predictions for solar system objects the Vera C.\ Rubin Observatory Legacy Survey of Space and Time (LSST) will not detect over its ten-year baseline survey. Employing s…
Predictions of Imminent Earth Impactors Discovered by LSST
Ian Chow, Mario JuriÄ, R. Lynne Jones +5
Imminent impactors are natural bodies discovered in space before impacting the Earth. They provide a rare opportunity to characterize individual near-Earth objects (NEOs) in great…
Assessing the Vera Rubin Observatory's Ability to Discover Asteroid Impactors Before They Collide with Earth
Qifeng Cheng, Daniel Scolnic, Jacob A. Kurlander +2
Asteroid impactors larger than ~10 m, from Chelyabinsk-scale airburst and Tunguska-scale events to >300 m continental threats, remain the dominant planetary-defense risk. While the…
Decameter-sized Earth Impactors -- II: A Bayesian Inference Approach to Meteoroid Ablation Modeling
Ian Chow, Peter G. Brown
Small asteroids and large meteoroids frequently impact the Earth, though their physical and material properties remain poorly understood. When observed as fireballs in Earth's atmo…
Influence of Modeling Assumptions on the Inferred Dynamical State of Resonant Systems: A Case Study of the HD 45364 System
Ian Chow, Sam Hadden
Planetary systems exhibiting mean-motion resonances (MMRs) offer unique opportunities to study the imprint of disk-induced migration on the orbital architectures of planetary syste…
Decameter-sized Earth impactors -- I: Orbital properties
Ian Chow, Peter G. Brown
Numerous decameter-sized asteroids have been observed impacting Earth as fireballs. These objects can have impact energies equivalent to hundreds of kilotons of TNT, posing a hazar…
