Radiants and orbits of Geminids observed by the European Fireball Network
Original language description
Precise radiants and orbits of bright Geminid meteors observed by the digital cameras of the European Fireball Network in the recent years are presented. When corrected for the radiant motion, most individual radiants fall within an area of a diameter of one degree. The radiants in the east-south-eastern part of that area belong to meteoroids with smaller semimajor axes and larger arguments of perihelia. We can distinguish a core of the stream with semimajor axes between 1.25 AU and 1.30 AU and a wing with semimajor axes up to 1.39 AU. The core is more concentrated in eccentricities and perihelion distances than the wing. Both core and wing meteoroids are encountered during the whole duration of the shower. The wing contains smaller meteoroids on average. Therefore, an opposite trend than expected from the action of the Poynting–Robertson effect, which decreases semimajor axes of small meteoroids, is present in Geminids, as noted already by (Spurný 1993). We hope that our new observations together with a modeling effort will shed light on the formation and evolution of the stream.
