High Throughput Analysis of Nanobeam Electron Diffraction Datasets using Unsupervised Clustering
Ian MacLaren, Ala Al-Afeef, Trevor Almeida +5
If disk detection is applied to nanobeam electron diffraction datasets, then the results are effectively a list of vectors describing the position of every diffraction peak in real…
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…
Towards establishing best practice in the analysis of hydrogen and deuterium by atom probe tomography
Baptiste Gault, Aparna Saksena, Xavier Sauvage +42
As hydrogen is touted as a key player in the decarbonization of modern society, it is critical to enable quantitative H analysis at high spatial resolution, if possible at the atom…
The Winchcombe Fireball -- that Lucky Survivor
Sarah McMullan, Denis Vida, Hadrien A. R. Devillepoix +34
On February 28, 2021, a fireball dropped kg of recovered CM2 carbonaceous chondrite meteorites in South-West England near the town of Winchcombe. We reconstruct the fireb…
Dynamic Trajectory Analysis of Meteoroids Showing Minimal Deceleration
Thomas Stevenson, Ellie Sansom, Hadrien Devillepoix +8
Meteoroids decelerate and ablate as they descend through the atmosphere, however a portion of instrumentally observed meteors show little measurable deceleration and remain poorly…
