Especially, we focus on the formation process of compound chondrules by collisions. In the shock wave heating process, stripping off of liquid surface from partially molten dust particles, and the break up of totally molten particles can happen due to the gas dynamical pressure. The stripped off droplets and the fragments of the break up, which are called 'secondary particles' here, are expected to have rather small relative velocity each other, that is needed to form compound chondrules by collisions. Estimating the velocity of those particles based on a simple assumption that the flow velocity in the liquid part of the molten particle determines it, we have found that the velocity is small enough for almost all the shock waves that can heat and melt the dust particles to form chondrules. Thus, it seems possible that collisions among secondary-secondary and primary-secondary dust particles would form compound chondrules. This is a new mechanism for compound chondrule formation., 資料番号: AA0063505005}, pages = {17--20}, publisher = {宇宙航空研究開発機構宇宙科学研究本部, Institute of Space and Astronautical Science, Japan Aerospace Exploration Agency (JAXA/ISAS)}, title = {Stripping off a liquid surface of molten particles and formation of compound chondrules}, year = {2006} }
