Long-Term Continuous Double Station Observation of Faint Meteor Showers
Meteor detection and analysis is an essential topic in the field of astronomy. In this paper, a high-sensitivity and high-time-resolution imaging device for the detection of faint meteoric events is presented. The instrument is based on a fast CCD camera and an image intensifier. Two such instruments form a double-station observation network. The MAIA (Meteor Automatic Imager and Analyzer) syst...

متن کاملDetermination of meteor showers on other planets using comet ephemerides
Meteor showers on the Earth occur at well known times, and are associated with the decay of comets or other minor bodies whose orbital paths pass close to the Earth’s trajectory. On the surface, determining the closest proximity of two orbital paths appears to be a computationally intensive procedure. This paper describes a simple geometric method for determining the proximity between the orbit...
متن کاملA new method to predict meteor showers II. Application to the Leonids
Our model of meteor shower forecasting (described in Paper I) is applied to the Leonid shower. This model is based on the “dirty snowball” model of comets, and on heavy numerical simulation of the generation and evolution of meteoroid streams. The amount of dust emitted by comet 55P/Tempel-Tuttle is computed. A statistical weight is associated to each simulated particle. This weight represents ...
متن کاملPerformance of D-parameters in isolating meteor showers from the sporadic background
It is often necessary to draw a division between meteor showers and the sporadic meteor complex in order to study these components of the meteoroid environment. Meteor showers persist for less than a season and are composed of members with a greater-thanaverage degree of orbital similarity. The level of orbital similarity is often quantified using so-called D-parameters; a D-parameter cutoff ma...
