Description
Summary:The results of numerical simulations of small meteoroid impacts against the rocky lunar surface are presented which give an estimate of impact luminous efficiency. The obtained values of luminosity can considerably differ from the real ones because of the influence of regolith. Specific features of impacts into the regolith are discussed and a simple model discribing the shock wave structure in the porous target is proposed.
