Observational Study of the Structure of Stellar Envelopes and Circumstellar Envelopes.

本研究计划通过在美国和澳大利亚的海外观测获得恒星包络的观测数据。今年是过去两年活动的总结年。我们于1990年1月17-19日在京都大学组织了一次恒星物理科学会议，会议分四个部分介绍了观测结果：（1）早型星，（2）晚型星，（3）主序前天体，（4）双星，每一部分都取得了足够的进展。

The present research program has been organized to get observational data on the envelopes of stars through oversea observations in U.S.A. and Australia.In this year, as the year of summarization for the past 2-year activities. We organized a scientific meeting on stellar physics, at the Kyoto University, 17-19 January, 1990, where the results of observations were presented in 4 sessions: (1) Early type stars, (2) late type stars, (3) pre-main sequence objects, and (4) binaries.Sufficient progress has been attained in each session.
