内容記述 | Shock waves generated in the protoplanetary nebula heat dust particles there due to the gas drag. If the gas drag heating is strong enough to melt silicates, they solidify after melting and form chondrules, which are spherical components universally contained in chondritic meteorites. We performed numerical simulations of the molten droplet exposed to the high-speed rarefied gas flow taking into account the effect of rotation, and derived the surface deformation of the droplet. We found that the external shape of the droplet well matches with some measured chondrules in the cases that the droplet rotates in the gas flow. | |||||
