Radar and Infrasound Observations of the 2026 May 30 Cape Cod Bay Superbolide
Juha Vierinen, Ryan Volz, Marc Fries +10
Metre-scale impactors connect near-Earth-object dynamics, atmospheric-entry physics and meteorite delivery, but their pre-impact orbits and material properties are rarely measured…
Altitude-Dependent Near-Source Spectral Filtering of Meteor Infrasound Above 80 km and Consequences for Period-Based Energy Estimates
Elizabeth A. Silber, Igor P. Chunchuzov, Oleg E. Popov +1
Infrasound signal period is widely used as a proxy for source energy in bolide studies, but the reliability of period-yield relations for small, high-altitude regional meteors has…
Asteroid Disruption and Deflection Simulations for Multi-Modal Planetary Defense
Alexander N. Cohen, Philip Lubin, Darrel Robertson +7
Planetary defense from asteroids via deflective means alone does not offer viable solutions in terminal scenarios where there is little warning time before impact. The PI method of…
Optical and acoustic ground effects simulations from terminal defense asteroid disruption via the PI method
Brin Bailey, Alexander N. Cohen, Philip Lubin +5
Our simulations suggest that PI ("Pulverize It"), a NASA Phase II NIAC study, is an effective multi-modal approach for planetary defense that can operate in extremely short interdi…
The Role of Source Geometry and Atmospheric Propagation in Global Bolide Infrasound Detectability
Miro Ronac Giannone, Elizabeth A. Silber
Global infrasound monitoring provides a persistent means of detecting energetic bolide atmospheric entries, complementing optical observations and extending coverage over remote re…
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…
Benchmarking Cylindrical Blast Wave Theory Against the OSIRIS-REx Sample Return Capsule Reentry
Elizabeth A. Silber
Weak shock theory based on cylindrical blast waves has been used to interpret meteor infrasound, but it has not been systematically benchmarked against a non-ablating hypersonic so…
