OPTICAL PREDICTIONS FOR HIGH GEOCENTRIC VELOCITY METEORS

In this study we numerically modelled the atmospheric ablation and luminosity of cometary structure meteoroids with geocentric velocities from 71 to 200 km/s. We considered meteoroid masses ranging from 10−13 to 10−6 kg. Expected heights of ablation and maximum luminosity absolute magnitudes are det...

Description
Summary:In this study we numerically modelled the atmospheric ablation and luminosity of cometary structure meteoroids with geocentric velocities from 71 to 200 km/s. We considered meteoroid masses ranging from 10−13 to 10−6 kg. Expected heights of ablation and maximum luminosity absolute magnitudes are determined. Height and trail length values are used to calculate the angle traversed in a single video frame. It is found that for pre-atmospheric meteoroid masses of greater than 10−8 kg, high geocentric velocity meteors should be detectable with current electro-optical technology if properly optimised.
