论文摘要

原月球磁盘中的仪表大小的屏障是行星形成的主要挑战,为此提出了许多溶液。领先的解决方案之一是尘埃陷阱,它停止或减慢灰尘颗粒的内在迁移。这些陷阱的来源和轮廓仍然不完全知道。扭曲的磁盘在总体上,尤其是原始磁盘中无处不在,并且扭曲可能自然导致尘埃陷阱的形成。扭曲磁盘中的尘埃陷阱不仅可能从压力梯度上升,而且由于气体和灰尘之间的进动率不同。在这里,我们通过分析扭曲的磁盘中的径向漂移得出,并在某些特定条件下证明了推导。翘曲的原球磁盘中的径向漂移在质上有所不同,根据磁盘的结构,由于翘曲而形成尘埃陷阱。类似的过程也可能导致在其他积聚磁盘(例如AGN磁盘)中形成陷阱。

The meter-size barrier in protoplanetary disks is a major challenge in planet formation, for which many solutions were suggested. One of the leading solutions is dust traps, that halt or slow the inward migration of dust particles. The source and profile of these traps are still not completely known. Warped disks are ubiquitous among accretion disks in general and protoplanetary disks in particular, and the warping could lead naturally to the formation of dust traps. Dust traps in warped disks could rise not only from pressure gradients, but also due to different precession rates between gas and dust. Here we derive analytically the radial drift in warped disks, and demonstrate derivation for some specific conditions. The radial drift in warped protoplanetary disks is qualitatively different, and depending on the structure of the disk, dust traps could form due to the warping. Similar processes could lead to the formation of traps also in other accretion disks such as AGN disks.
