Global Monitoring and Characterization of Infrasound Signatures by Large Fireballs
Atmosphere, 2020 Large meteoroids can be registered in infrasound recordings during their entry into the Earth’s atmosphere. A comprehensive study of 10 large fireball events of the years 2018 and 2019 highlights their detection and characterization using global ...

Meteoroid Engineering Model (MEM): A Meteoroid Model For The Inner Solar System [PDF]
Earth, Moon, and Planets, 2004 In an attempt to overcome some of the deficiencies of existing meteoroid models, NASA’s Space Environments and Effects (SEE) Program sponsored a 3 year research effort at the University of Western Ontario. The resulting understanding of the sporadic meteoroid environment – particularly the nature and distribution of the sporadic sources – were then ...

Assessing the meteoroid risk in near earth space
Open Astronomy, 2018 The meteoroid risk in circumterrestrial space is basically caused by 1-10 mm meteoroid bodies. Meteoroid particles of such dimensions cannot be registered by modern monitoring astronomical instruments.

Streamlets within meteoroid streams on NEA orbits [PDF]
Geofísica Internacional, 2008 Five meteoroid streams of apparent asteroidal nature have been identified in the IAU_MDC Database of Photographic Meteors. Three streams contain streamlets, composed of two or more meteoroids sharing nimpact rate on the NEA population by objects 1 m or ...

Flexoelectricity in Photoconversion: Fundamentals, Materials, and Outlooks
Advanced Science, EarlyView.Mechanical bending of a flexible cantilever induces a strain gradient in the photoactive material. The resulting flexoelectric field couples with photovoltaic and photoconductive effects, modulating charge generation, separation, and collection. A comparative analysis of oxide perovskites, halide perovskites, and two‐dimensional materials is presented,

A Near-Earth Object Model Calibrated to Earth Impactors
The Astronomical JournalThe population of Earth-impacting meteoroids and their size-dependent orbital elements are key to understanding the origin of meteorites and informing planetary defense efforts. Outstanding questions include the role of collisions in depleting meteoroids
