Revealing Physical Properties of Protoplanetary Disks from Theory and Observations

了解原行星盘的物理特性对于理解行星形成的场景是很重要的。最近的观测揭示了原行星盘中的一些非轴对称、凹凸不平的结构。该项目的主要目标是：(1)基于近红外和毫米/亚毫米波长的最新观测，探索原行星盘的“现实”模型；(2)（重新）研究原行星盘的基本物理过程，并在理论和观测之间建立联系。为了实现目标(1)，我们参与了对斯巴鲁采集的数据或ALMA早期观测数据的讨论，这些数据显示出有趣的形态结构，如环状或螺旋形。为了实现目标(2)，我们进行了理论研究，包括盘-行星相互作用和间隙形成过程的研究。

Understanding the physical properties of protoplanetary disks is important in understanding planet formation scenario. Recent observations have revealed several non-axisymmetric, bumpy structures in protoplanetary disks.The main goals of this project are (1) to explore what the "realistic" models are for protoplanetary disks based on the most recent observations at NIR and mm/sub-mm wavelengths, and (2) to (re-)investigate the fubndamental physical processes in protoplanetary disks and make the link between the theory and observations.To achieve the goal (1), we have been involved in the discussions of the data taken by Subaru or the early observations of ALMA, which show interesting morphological structures such as rings or spirals. To achieve the goal (2), we have done theoretical studies including the investigations of disk-planet interaction and gap formation processes.
