内容記述 | The solar system is understood to have formed by the continued infall of interstellar gas and dust to an accretion disk (=the solar nebula). The interstellar material would encounter the nebula at nearly the free-fall velocity, and would have very great kinetic energy. Dust particles falling through the nebula would dissipate their mechanical energy as heat, as they experienced aerodynamic drag in the nebular gases. Heating and deceleration are calculated for a simple infall model. It is found that 1-mm dust aggregations falling into the present zone of the terrestrial planets would be melted, and would cool at ∿350K/hr. Dynamic crystallization experiments have shown that the crystalline textures of meteoritic chondrules were produced during cooling at a similar rate. | |||||||
