First 3‐D simulations of meteor plasma dynamics and turbulence
(American Geophysical Union, 2015-01-11)
Millions of small but detectable meteors hit the Earth's atmosphere every second, creating trails of hot plasma that turbulently diffuse into the background atmosphere. For over 60 years, radars have detected meteor plasmas ...
Catálogo de los meteoritos hallados en territorio argentino
(Fundación Félix Azara, 2011-07)
Es presentado aquí el primer catálogo de meteoritos argentinos. El listado actualizado incluye varios especímenes no reportados previamente. En total se mencionan setenta y cuatro ejemplares, caídos ó encontrados. Fueron ...
A radio science perspective on long-duration meteor trails
(American Geophysical Union, 2007-12-27)
Nonclassical radar meteor echoes or range spread trail echoes (RSTEs), lasting from tens of seconds to over 15 min, have been a subject of considerable interest and speculation in the community ever since they were first ...
Meteor velocity determination with plasma physics
(European Geosciences Union (EGU), 2004-06-03)
Understanding the global meteor flux at Earth requires the measurement of meteor velocities. While several radar methods exist for measuring meteor velocity, they may be biased by plasma reflection mechanisms. This paper ...
Campo del Cielo. La Gran Lluvia Meteorítica
(Servicio Geológico Minero Argentino. Instituto de Geología y Recursos Minerales, 2008)
Los meteoroides son cuerpos rocosos menores que forman parte de los sistemas planetarios. Su tamaño varía desde pocos milímetros hasta grandes masas de varias toneladas de peso. Se desplazan a enormes velocidades por el ...
Vichada meteorite impact effects from simulation of regional environmental consequences of a meteoroid impact on Earth
(Universidad Nacional de Colombia - Sede Bogotá - Facultad de Ciencias - Departamento de Geociencia, 2018-01-01)
This study estimates the regional environmental consequences of the impactor extraterrestrial body that could produce the probable Vichada impact crater structure on the Vichada Plain, in Colombia, South America. This paper ...
Production and fate of the G ring arc particles due to Aegaeon (Saturn LIII)
(2018-04-21)
The G ring arc hosts the smallest satellite of Saturn, Aegaeon, observed with a set of images sent by Cassini spacecraft. Along with Aegaeon, the arc particles are trapped in a 7:6 corotation eccentric resonance with the ...
Meteor trail diffusion and fields: 2. Analytical theory
(American Geophysical Union, 2006-12-20)
A meteoroid penetrating the Earth's atmosphere leaves behind a trail of dense plasma embedded in the lower E/upper D region ionosphere. While radar measurements of meteor trail evolution have been collected and used to ...

Catalogue of Meteorites from South America
(Springer Verlag Berlín, 2014)
The first Catalogue of Meteorites from South America is presented here. The updated list includes many new specimens previously never reported. The total number of specimens mentioned is 600, falls or finds. Doubtful ...
