Institute of Space and Astronautical Science, Japan Aerospace Exploration Agency (JAXA)(ISAS)), Sagamihara, Kanagawa Japan, To know the formation process of cosmic dust particles, we attempted for the first time interferometric observation to a condensation experiment in vapor phase, the gas evaporation method. Homogeneous nucleation is a fundamental process of dust formation in universe. For the first step, temperature distribution around evaporation source was measured with respect to the source temperature in the gas evaporation method for the first time in a quarter century. We visualized a condensation of smoke particles in gas phase and temperature history including a cooling rate of produced particles after nucleation was recognized. Homogeneously condensed WO3 nuclei initially maintain their temperature for ca.5 ms and then cool down with a rate of ca.5×10(exp 4) K/s. The degree of supersaturation during the nucleation was at least as high as 10(exp 7)., 形態: カラー図版あり, Physical characteristics: Original contains color illustrations, 資料番号: AA0065129019}, pages = {47--50}, publisher = {宇宙航空研究開発機構宇宙科学研究所 (JAXA)(ISAS), Institute of Space and Astronautical Science, Japan Aerospace Exploration Agency (JAXA)(ISAS)}, title = {宇宙ダスト生成過程の解明に向けた気相からの均質核形成のその場観察実験}, volume = {27}, year = {2011} }
