研究了外部重力在有限厚度等温盘中的波激发。这项研究的主要应用是阐明原行星在原行星盘中角动量传递的过程。研究发现，具有垂直运动的波（3D 波）和没有垂直运动的波（2D 波）都会被激发，并且这两种波都可以传递角动量。二维波具有与无限薄圆盘中的波相似的特性。盘中心平面上的原行星主要激发二维波。另一方面，3D 波对角动量传递影响较小。
Wave excitation in isothermal disks with finite thickness by external gravity is investigated. The main application of this study is to clarify the process of angular-momen tum transfer in a protoplanetary disk by a protoplanet. It is found that waves with vertical motion (3D-waves) as well as waves without vertical motion (2D-waves) are excited, and that both waves can transfer angular-momentum. The 2D-waves have properties similar to the waves in infinitesimal ly thin disks. A protoplanet on the central plane of the disk excites mainly 2D-waves. On the other hand, 3D-waves have a minor effect on the angular-momentum transfer.
