Shock wave formation in the thermosphere by an earthgrazing fireball: Empirical evidence for volatile-enhanced hydrodynamic shielding
Elizabeth A. Silber, Denis Vida, Miro Ronac Giannone +7
Hydrodynamic shielding is a theoretically well-established but observationally elusive and experimentally difficult-to-replicate phenomenon with implications that extend far beyond…
A Search for Hydroacoustic Signals from Bolides
P. Brown, L. McFadden, D. McCormack +2
Here we present a survey aimed at detecting hydroacoustic signals from fireballs using the six hydrophone stations operated as part of the Comprehensive Test Ban Treaty Organisatio…
Meteor statistics I: The distribution of instrumental magnitudes
Althea V. Moorhead, Peter G. Brown, Margaret D. Campbell-Brown +2
The distribution of meteor magnitudes is known to follow an exponential distribution, where the base of this distribution is called the population index. The distribution of observ…
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…
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…
A Statistical Approach to Quantifying Uncertainty in Meteoroid Physical Properties
Maximilian Vovk, Denis Vida, Peter G. Brown
Meteoroid bulk density is a critical value required for assessing impact risks to spacecraft, informing shielding and mission design. Direct bulk density measurements for sub-milli…
