Outline of Final Research Achievements

Impact-generated ejecta curtains produced by hypervelocity impacts onto planets are investigated using experimental, analytical and numerical methods. It is found that no large-scale discharge structures are generated in typical spatial and time scales of laboratory impact experiments. The analytic and numerical models were developed to analysis the mutual collisions between the constituent micro particles of ejecta curtains. We have reproduced the mesh-like patterns of ejecta curtains observed in the laboratory experiments. In the future, we will investigate the possibility whether lightning discharges occur in ejecta curtain.

Academic Significance and Societal Importance of the Research Achievements

大気を持たない太陽系の固体惑星, 衛星の表面を支配する地形は衝突クレータである. それらの形成時には必然的に放出物カーテンが発生していたであろう.放出物カーテンの発生, 成長, 堆積は1つの地質過程として認識されている. 今回の萌芽研究によって, 天体衝突で発生する放出物カーテンの様々な特性が明らかとなったことによって, 地質過程の新たな理解が得られた.
