由云-云碰撞触发的恒星/行星形成的SPH模拟
SPH simulations of star/planet formation triggered by cloud-cloud collisions
摘要:
我们目前的结果,流体动力学模拟的恒星形成触发的云-云碰撞。在恒星形成的早期阶段,低质量的天体在原恒星盘中由于引力不稳定而形成。这些低质量物体中有一些在亚恒星质量范围内,包括一些行星质量的物体。在我们的模拟中,导致低质量物体形成的盘不稳定性是盘与盘之间相互作用和/或盘与周围气体之间相互作用的产物。
英文摘要:
We present results of hydrodynamic simulations of star formation triggered by cloud-cloud collisions. During the early stages of star formation, low-mass objects form by gravitational instabilities in protostellar discs. A number of these low-mass objects are in the sub-stellar mass range, including a few objects of planetary mass. The disc instabilities that lead to the formation of low-mass objects in our simulations are the product of disc-disc interactions and/or interactions between the discs and their surrounding gas.
