Localizing the First Interstellar Meteor with Seismometer Data
Signals, 2023 The first meter-scale interstellar meteor (IM1) was detected by US government sensors in 2014, identified as an interstellar object candidate in 2019, and confirmed by the Department of Defense (DoD) in 2022.

Time/Frequency Analysis of Terrestrial Impack Crater Records [PDF]
Journal of Astronomy and Space Sciences, 2006 The terrestrial impact cratering record recently has been examined in the time domain by Chang & Moon (2005). It was found that the ˜ 26 Myr periodicity in the impact cratering rate exists over the last ˜ 250 Myrs.

The sporadic radiant and distribution of meteors in the atmosphere as observed by VHF radar at Arctic, Antarctic and equatorial latitudes [PDF]
Annales Geophysicae, 2009 Results are presented of a study of the temporal and spatial variability in meteor count rate observations from three VHF meteor radars. These radar are located in the Arctic (at Esrange, 68° N), in the Antarctic (at Rothera, 68° S) and near ...

Determination of meteor-head echo trajectories using the interferometric capabilities of MAARSY [PDF]
Annales Geophysicae, 2013 During the flight of a meteoroid through the neutral atmosphere, the high kinetic energy is sufficient to ionize the meteoric constituents. Radar echoes coming from plasma irregularities surrounding the meteoroids are called meteor-head echoes, and ...

Thermalization of Sputtered Particles as the Source of Diffuse Radiation from High Altitude Meteors [PDF]
, 2005 High altitude meteors become luminous at altitudes above $\sim$130 km, where the standard ablation theory of meteor light production is not applicable. The physical mechanism responsible for their glow has not been known. We present a model that explains
