Three-body resonance in meteoroid streams [PDF]

open access: yes, 2016
Mean-motion resonances play an important role in the evolution of various meteoroid streams. Previous works have studied the effects of two-body resonances in different comets and streams. These already established two-body resonances were mainly induced

Robotic Systems for Meteor Observing and Moon Impact Flashes Detection in Spain

open access: yesAdvances in Astronomy, 2010
A robotic observatory has been setup in the south-west of Spain with the aim to study meteoroids interacting with the Earth's atmosphere and meteoroids impacting on the Moon's surface.

Determination of meteoroid physical properties from tristatic radar observations [PDF]

open access: yesAnnales Geophysicae, 2008
In this work we give a review of the meteor head echo observations carried out with the tristatic 930 MHz EISCAT UHF radar system during four 24 h runs between 2002 and 2005 and compare these with earlier observations.

Global Monitoring and Characterization of Infrasound Signatures by Large Fireballs

open access: yesAtmosphere, 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 ...

An introduction to the Meteor and ionospheric Irregularity Observation System and its preliminary results

open access: yes地球与行星物理论评
Meteoroids entering the Earth's atmosphere lose most of their mass during atmospheric passage and considerably disturb the background ionosphere. To elucidate better the effects of meteoroids on the near-Earth space environment, it is important to ...

Minor Planet Databases

open access: yesOpen Astronomy, 2015
We cast a retrospective look at the mankind’s acquaintance with minor bodies of the Solar System, at the explosive growth in their discoveries resulting from the technological progress, and at gradual understanding of the danger to our very existence ...

Reconciling the dawn-dusk asymmetry in Mercury's exosphere with the micrometeoroid impact directionality

open access: yes, 2017
Combining dynamical models of dust from Jupiter Family Comets and Halley-type Comets, we demonstrate that the seasonal variation of the dust/meteoroid environment at Mercury is responsible for producing the dawn-dusk asymmetry in Mercury's exosphere ...

Meteoroid structure and fragmentation [PDF]

open access: yesPlanetary and Space Science, 2019
The physical composition and structure of meteoroids gives us insight into the formation processes of their parent asteroids and comets. The strength of and fundamental grain sizes in meteoroids tell us about the environment in which small solar system bodies formed, and the processes which built up these basic planetary building blocks.

Assessing the meteoroid risk in near earth space

open access: yesOpen 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.

Meteor showers of comet C/1917 F1 Mellish

open access: yes, 2010
December Monocerotids and November Orionids are weak but established annual meteor showers active throughout November and December. Analysis of a high quality orbits subset of the SonotaCo video meteor database shows that the distribution of orbital ...
