| Outline of Final Research Achievements |
Meteoroids whose diameters are between μm and m are thought to be originated from comets and asteroids. On the other, there is little knowledge of connection between meteoroids, meteorites and parent asteroids. Spectroscopic observation of ultra-high-speed, 10s km/s, atmospheric entry of meteoroids enable us to investigate time variations of atomic and molecular emissions, exciting temperature, abundance and so on. The purpose of this study is to understand the relation between small bodies such as asteroids, comets and meteoroids from their interplanetary orbits, mass, species and flux rate by using ultrahigh-sensitivity and high-resolution meteor spectroscopic-imaging cameras together with a high-power large-aperture meteor head-echo radar, laboratory simulation of meteor ablation and telescopic observations of meteor parent bodies.
