中文摘要
考虑到尘埃粒子内部密度的演化,我们研究了尘埃粒子到行星体的生长过程以及它们的径向迁移。由于它们的径向迁移,固体集中在10AU内,并成长为千米大小的小行星。在这个小行星形成区,固体组分的表面密度比原始值提高了约10倍。生长中的固体具有高度多孔的结构,这有助于它们生长到小行星上。固体表面密度的大幅增加加速了木星行星核心的生长。
英文摘要
We investigated the growth process from dust grains to planetesimals and their radial migration, taking into account the evolution of their internal density. Because of their radial migration, solid bodies are concentrated inside of 10AU and grow to km-sized planetesimals. In this planetesimal-forming region, the surface density of the solid component is enhanced by a factor of ~10, compared with the original value. The growing solid bodies have a highly porous structure, which helps their growth to planetesimals. The large enhancement in the solid surface density accelerates growth of cores of Jovian planets.
