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…
Inferring Meteoroid Properties with Dynamic Nested Sampling: A Case Study of Orionid and Capricornid Shower Meteors
Maximilian Vovk, Peter G. Brown, Denis Vida +2
Accurate estimation of meteoroid bulk density is crucial for assessing spacecraft impact hazards from sub-millimeter to millimeter-sized meteoroids. Previous studies often used man…
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…
A Near-Earth Object Model Calibrated to Earth Impactors
Sophie E. Deam, Hadrien A. R. Devillepoix, David Nesvorný +16
The population of Earth-impacting meteoroids and its size-dependent orbital elements are key to understanding the origin of meteorites and informing on planetary defence efforts. O…
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…
