The purpose of this project is to clarify the dynamical phenomena in stellar evolution by the high precision astrophysical observations. For such high precision observations, not onlt good whether but also dark and dry sites with good seeing are needed, and such conditions can be fulfilled only by several astronomical observatories in the world. For this reason, we have organized this project to observe by the large telescopes located at such good observing sites in the worlds. The best of these are found at the sumits of Mauna Kea in Hawai and of Andes in Chili. Also, there are several good sites in North America and in Australia. We have sent more than 10 observing teams to these best astronomical sites in the worlds and obtaind very useful data to investigate the dynamical phenomena in stars. Based on these data, dynamical phenomena during the star formation, in close bimary system, and in late stages of stellar evolution are being clarified.

该项目的目的是通过高精度天体物理观测来阐明恒星演化的动力学现象。如此高精度的观测，不仅需要良好的天气条件，还需要黑暗、干燥、视宁度良好的场地，而这样的条件，世界上只有几个天文台能够满足。为此，我们组织了这个项目，利用世界上如此好的观测地点的大型望远镜进行观测。其中最好的发现于夏威夷的莫纳克亚山和智利的安第斯山脉的山顶。此外，北美和澳大利亚也有一些不错的网站。我们派出了10多个观测小组前往这些世界上最好的天文地点，并获得了非常有用的数据来研究恒星的动力学现象。基于这些数据，恒星形成过程中、封闭双星系统中以及恒星演化后期的动力学现象正在被阐明。
