Catastrophic disruption of asteroid 2023 CX1 and implications for planetary defense
Auriane Egal, Denis Vida, François Colas +94
Mitigation of the threat from airbursting asteroids requires an understanding of the potential risk they pose for the ground. How asteroids release their kinetic energy in the atmo…
Luminous efficiency based on FRIPON meteors
Esther Drolshagen, Theresa Ott, Detlef Koschny +36
In meteor physics the luminous efficiency is used to convert the meteor's magnitude to the corresponding meteoroid's mass. However, lack of sufficiently accurate verification…
Perihelion history and atmospheric survival as primary drivers of the Earth`s meteorite record
Patrick M. Shober, Hadrien A. R. Devillepoix, Jeremie Vaubaillon +7
Models predict that more than half of all impacting meteoroids should be carbonaceous, reflecting the abundance of carbon-rich asteroids in the main belt and near-Earth space. Yet…
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…
The Formation and Evolution of Ordinary Chondrite Parent Bodies
Pierre Vernazza, Brigitte Zanda, Tomoki Nakamura +2
Ordinary chondrites (OCs) are by far the most abundant meteorites (80% of all falls). Their origin has long been the matter of a heated debate. About thirty years ago (e.g., Pellas…
Fine-scale observations of the Doppler frequency shifts affecting meteor head radio echoes
Jean-Louis Rault, Mirel Birlan, Cyril Blanpain +11
The French FRIPON (Fireball Recovery and Interplanetary Observation Network) programme relies on a video cameras network associated to radio sensors running in a radar multistatic…
