项目摘要

Infrared Space Observatory (ISO) launched in Nov.1995 by the European Space Agency (ESA) is the world's first true astronomical observatory in space, operated at infrared wavelengths. The purpose of the present International Scientific Research Program is to clarify the formation of the primavel galaxies and stellar evolution in the formation phase as well as in the latest stage, by the infrared observations with the use of this highly efficient ISO satellite.We have proposed many proposals along with our purposes above and a part of them have been already completed. The main results so far obtained are :1. Multi-wavelength deep survey for primavel galaxies was very successful and tens of such candidated were observed,2. Spectral mapping of the photodissociation regions by the fine structure lines showed that the distribution of heavy atoms and ions is different from that of hydrogen,3. Systematic spectral observations along red giant branch leads the discovery of warm molecular envelope above the photospere in late M giants and Mira variables. This envelope could play an significant role in understanding the mass loss phenomenona in the late stage of stellar evolution,4. Systematic multi-band photometries of the globlar clusters in the Magellanic Clouds resulted in the discovery of infrared stars which is thought to experience heavy mass loss. These stars will be used to test the current evolution theory.

红外空间天文台（ISO）于1995年11月由欧洲航天局（ESA）发射，是世界上第一个真正的空间天文台，在红外波长下运行。本国际科学研究计划的目的是利用这颗高效率的国际标准化组织卫星进行红外观测，阐明原始星系的形成和恒星在形成阶段和最后阶段的演化。根据上述目的，我们提出了许多建议，其中一部分已经完成。目前得到的主要结果是：1。对primavel星系的多波长深巡天非常成功，观测到数十个这样的候选星系。光解区精细结构谱图表明，重原子和重离子的分布与氢的分布不同。沿着红巨星分支进行系统的光谱观测，在M晚期巨星和Mira变星的光球球上方发现了温暖的分子包膜。这个包层可以在理解恒星演化后期的质量损失现象方面发挥重要作用。对麦哲伦星云中的球状星团进行系统的多波段光度测量，发现了被认为经历了严重质量损失的红外恒星。这些恒星将被用来检验目前的进化论。
