Institute of Space and Astronautical Science, Japan Aerospace Exploration Agency (JAXA)(ISAS)), Sagamihara, Kanagawa Japan, Exogenic delivery of organic molecules by cometary/asteroidal impacts is one of the most important candidates for organic supply on prebiotic Earth. Its mechanism, however, is not simple; most of organics originally contained in impacting objects are decomposed by initial impact heating and subsequent interaction of ambient atmosphere. Such decomposed organics may actually lead to synthesis of simple but chemically active organic molecules within impact vapor plumes, particularly for oblique impacts. The details of physical and chemical processes in the cloud, nevertheless, are not understood well yet. Thus, we conducted time-series spectroscopic and band-pass imaging observation of vapor clouds due to oblique impacts using a two-stage light gas gun to characterize their thermodynamic conditions. We measured velocity and blackbody temperature of these clouds as functions of time. Obtained data indicate that high-speed projectile fragments are vaporized at much higher rate than previous estimates. Such high vaporization efficiency may lead to higher rate of organic production within impact vapor plumes. Thus, such on-site organic resynthesize within impact-vapor clouds may have played a more important role in the origin of life than previously considered., 形態: カラー図版あり, Physical characteristics: Original contains color illustrations, 資料番号: AA0065116015},
