ダストの衝突合体成長 [HD] - YouTube 国立天文台４次元デジタル宇宙プロジェクト

It is widely believed that in protoplanetary disks, dust consisting of submicron-sized particles accumulates to form planets through repeated collisions and coalescences. This collisional growth process is, however, still unclear. It is one of the big remaining problems in the planetary formation theory. Here we introduce a movie of dust collisions based on numerical simulations.
