内容記述 | We carried out three-dimensional hydrodynamics simulations to examine disruption of a molten dust particle exposed to fast gas flow and estimated the ejection velocity, average size and number density of ejectors in the framework of the shock-wave heating model. We found that the collision frequency predicted from our numerical results is much higher than observational frequency of compound chondrules. We also detected collisions among ejectors in our simulations and understood that 'shadow effect' (the gas flow is blocked out by ejectors) is important for their collisions. These results strongly suggest that compound chondrules can be formed by nebula shocks. | |||||
