The Golden meteorite fall: Fireball trajectory, orbit, and meteorite characterization

Meteoritics &Planetary Science, Volume 58, Issue 12, Page 1773-1807, December 2023., 2023
Abstract The Golden (British Columbia, Canada) meteorite fall occurred on October 4, 2021 at 0534 UT with the first recovered fragment (1.3 kg) landing on an occupied bed. The associated fireball was recorded by numerous cameras permitting reconstruction of its trajectory and orbit. The fireball entered the atmosphere at a 54° angle from the horizontal

Linking meteorites to their asteroid parent bodies: The capabilities of dust analyzer instruments during asteroid flybys

Meteoritics &Planetary Science, Volume 58, Issue 10, Page 1449-1468, October 2023., 2023
Abstract Linking meteorites to their asteroid parent bodies remains an outstanding issue. Space‐based dust characterization using impact ionization mass spectrometry is a proven technique for the compositional analysis of individual cosmic dust grains.

The Transformation of Centaurs into Jupiter-family Comets

Astrophysical Journal, 2022
Centaurs are an ephemeral class of objects that can evolve into Jupiter-family comets (or JFCs) due to gravitational perturbations from the giant planets.
