原行星盘的内部区域

The inner regions of protoplanetary disks

C. P. Dullemond, J. D. Monnier

摘要:

要了解行星系统是如何在前主序星周围的尘埃盘中形成的,就需要对这些尘埃盘的结构和演化有详细的了解。虽然这是合理的理解为区域的磁盘超过约1 AU,这些磁盘的结构向内1 AU仍然是一个谜。这部分是因为用现有的望远镜很难在空间上分辨这些区域。但这也是因为对这个区域的物理学知之甚少,在这个区域,磁盘变得如此之热,以至于尘埃开始蒸发。近年来,红外线干涉测量法已经可以直接在空间上分辨出原行星盘的内部天文单位,尽管方法有些有限。这些观测结果部分证实了这些区域的现有模型,但也提出了新的问题和难题。此外,事实证明,这些区域的数值模拟极具挑战性。在这篇评论中,我们给出了一个粗略的概述的历史和最近的发展,在这个令人兴奋的领域的天体物理学。

英文摘要:

To understand how planetary systems form in the dusty disks around pre-main-sequence stars a detailed knowledge of the structure and evolution of these disks is required. While this is reasonably well understood for the regions of the disk beyond about 1 AU, the structure of these disks inward of 1 AU remains a puzzle. This is partly because it is very difficult to spatially resolve these regions with current telescopes. But it is also because the physics of this region, where the disk becomes so hot that the dust starts to evaporate, is poorly understood. With infrared interferometry it has become possible in recent years to directly spatially resolve the inner AU of protoplanetary disks, albeit in a somewhat limited way. These observations have partly confirmed current models of these regions, but also posed new questions and puzzles. Moreover, it has turned out that the numerical modeling of these regions is extremely challenging. In this review we give a rough overview of the history and recent developments in this exciting field of astrophysics.
