Meteor spectra and orbits at the Valašské Meziříčí Observatory

Popis výsledku v původním jazyce

Main goal in the meteors spectroscopy is to better understand the physical and chemical properties of meteoroids by using simultaneous video and spectral observations of meteors compared with meteoritic material laboratory spectra. Spectral observations of meteors are obtained via fixed (at Valašské Meziříčí Observatory) and mobile spectroscopic CCTV systems. All records of meteors and processing data (orbital elements, speed of deceleration, etc.) are inserted to EDMOND database (European viDeo MeteOr Network Database) together with spectral information. The exact orbits of the bolides for which the spectrum is recorded are very important information. In connection with the knowledge of the chemical composition of the body, they allow us to obtain a comprehensive overview of the properties of the bodies that ablate in the Earth's atmosphere. Simultaneously, our target is systematization of spectroscopic emission lines for the comparative analysis of meteor spectra. The solids will be irradiated using excimer and PALS lasers (Na, Ti, Mg,Al, Si, Fe, and Ca), their simple binary oxides, sulfides, minerals and real sample of meteorites. These spectra will be recorded in situ on the discharges and excimer laser ablations using Fourier time resolved high resolution spectrometer Bruker, high resolution Echelle spectrograph LLA and CCD spectrograph Ocean Optics. Complying data will allow for not only qualitative determinations of the impacting body composition but also the assignment of spectral lines for products from the meteorite alterations and plasma interactions in atmosphere.
