研究了磁驱动盘风(MDW)和热驱动光蒸发风(PEW)在原行星盘长期演化中的作用。我们从早期阶段开始模拟,在早期阶段,圆盘质量围绕着一颗恒星,并跟踪进化,直到圆盘完全分散。我们将质量损失PEW和质量损失和磁制动(风力矩)MDW,除了粘性吸积,粘性加热,和恒星辐射。我们发现,MDW和PEW,分别有不同的角色:磁驱动风蒸发材料从内部光盘在早期阶段,而光蒸发有一个主导作用,在后期阶段的外部(金Au)光盘。盘的寿命,这取决于MDW,PEW和粘性吸积的组合,表现出一个很大的变化100万至20万年;气体主要是分散的MDW和PEW在低粘度的情况下,寿命是敏感的质量损失率和扭矩的MDW,而寿命是不敏感的,当粘度高时,这些参数。即使在非常弱的湍流盘,MDW和PEW的合作,使光盘分散在几万年内。
We investigate the roles of magnetically driven disc wind (MDW) and thermally driven photoevaporative wind (PEW) in the long-time evolution of protoplanetary discs. We start simulations from the early phase in which the disc mass isaround astar and track the evolution until the disc is completely dispersed. We incorporate the mass-loss by PEW and the mass-loss and magnetic braking (wind torque) by MDW, in addition to the viscous accretion, viscous heating, and stellar irradiation. We find that MDW and PEW, respectively, have different roles: magnetically driven wind ejects materials from an inner disc in the early phase, whereas photoevaporation has a dominant role in the late phase in the outer (≳1 au) disc. The disc lifetime, which depends on the combination of MDW, PEW, and viscous accretion, shows a large variation of ∼1–20 Myr; the gas is dispersed mainly by the MDW and the PEW in the cases with a low viscosity and the lifetime is sensitive to the mass-loss rate and torque of the MDW, whereas the lifetime is insensitive to these parameters when the viscosity is high. Even in discs with very weak turbulence, the cooperation of MDW and PEW enables the disc dispersal within a few Myr.
