内容記述 | We simulate collisions of two planetesimals that are regarded as fluffy bodies. It is shown that the features of collisions depend strongly on the grain radius composing planetesimals. When two planetesimals collide each other at speed about 10 m/s, they are broken into pieces of grain radius of 0.1 micrometer. Since tensile strength of a planetesimal increases inversely proportional to the grain radius, the collisional displacement is reduced with decreasing grain radius. It is found that planetesimals consisting of grains of 0.1 micrometer or smaller are not destroyed by collisions. | |||||
