Streamlets within meteoroid streams on NEA orbits [PDF]

open access: yesGeofísica 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 ...

On associations of Apollo asteroids with meteor streams [PDF]

open access: yes
Potential associations of Apollo asteroids with meteor streams are searched on the basis of the orbital parameters comparison. From all Apollo asteroids discovered through 1991 June those are only selected for further analysis whose orbits approach to ...

Radiant measurement accuracy of micrometeors detected by the Arecibo 430 MHz Dual-Beam Radar [PDF]

open access: yesAtmospheric Chemistry and Physics, 2004
Precise knowledge of the angle between the meteor vector velocity and the radar beam axis is one of the largest source of errors in the Arecibo Observatory (AO) micrometeor observations. In this paper we study ~250 high signal-to-noise ratio (SNR) meteor

Meteor research program [PDF]

open access: yes
An overview of research on radio and radar meteors accomplished during the past decade is presented, and the work of the past year is highlighted. Velocity distribution and mass flux data are obtained for meteors in the range 10 to 0.0001 g, the size ...

Sternschnuppen und Erdmagnetismus, ein von Alexander von Humboldt und Carl Friedrich Gauß während der Universitätsfeierlichkeiten in Göttingen im September 1837 initiiertes Projekt

open access: yesHiN - Alexander von Humboldt im Netz. Internationale Zeitschrift für Humboldt-Studien, 2011
In September 1837 the centennial celebrations of Göttingen university took place; Alexander von Humboldt, who visited Göttingen for this purpose, and Carl Friedrich Gauss created the project: Do showers of meteors influence the terrestrial magnetic ...

The nonlinear thermodynamics of meteors, noctilucent clouds, enhanced airglow and global atmospheric circulation [PDF]

open access: yes
Two types of fundamental topological junctions of elements are deduced from a nonlinear thermodynamical model. Using this scheme, the possibility of a causal relation between fireballs and faint meteors as nonlinear sources on the one hand, and ...

MAIA: Technical Development of a Novel System for Video Observations of Meteors

open access: yesActa Polytechnica, 2011
A system for double station observation of meteors now known as MAIA (Meteor Automatic Imager and Analyzer) is introduced in this paper. The system is based on two stations with gigabite ethernet cameras, sensitive image intensifiers and automatic ...
