The meteor Database of observations in 2019–2021 with the automatical video and spectral meteor patrol of V. N. Karazin Kharkiv National University

Abstract

The Database of positional and spectral observations of meteors in 2019–2021 using the automatical video and spectral meteor patrol of the Institute of Astronomy of V. N. Karazin Kharkiv National University has analyzed. The kinematic parameters and elements of the heliocentric orbits of meteoroids were calculated using the methods of meteor astronomy according to the Observation Database. This work describes the methods of processing of spectral video observations. The software “AVSMP_Pro v1” for meteor spectra analysis has been created that allows to generate synthetic spectra and compare them with observed meteor spectra. The data from the NIST ASD electronic database (https://physics.nist.gov/PhysRefData/ASD/lines_form.html) is used for obtaining the composition of chemical elements in the meteoroid. As a result, we obtain an information about the relative quantitative chemical composition of meteoroids and the physical conditions of meteor plasma formation.
