Analysis of CN emission as a marker of organic compounds in meteoroids using laboratory simulated meteors

Fragments of small solar system bodies entering Earth’s atmosphere have possibly been important contributors organic compounds to the early Earth. The cyano radical (CN) emission from meteors is considered as potentially one most suitable markers in meteoroids, however, its detection meteor spectra has thus far unsuccessful. With aim improve our abilities identify CN observations and use spectral features characterize composition incoming asteroidal we present a detailed analysis high-resolution 22 laboratory simulated including ordinary, carbonaceous, enstatite chondrites, well large diversity achondrites (i.e., ureilite, aubrite, lunar, martian, howardite, eucrite, diogenite), mesosiderite, iron meteorites. We describe variations different classes analogues, correlation time evolution relative other major meteoroid components. demonstrate that can be used diagnostic feature carbonaceous carbon-rich while ordinary chondrites show no signs CN. Our results point out strong between H suggest both volatile are trace contents matter water molecules within meteoroids. For application lower resolution observations, best recognized stages ablation for materials by measuring intensity ratio band peak nearby Fe I-4 lines.
