项目摘要

Infrared Space Observatory (ISO) to be launched by European Space Agency (ESA) in autumn 1995 is the first true astronomical observatory in space, operated at infrared wavelengths. Since ISO is fully cooled and observations with ISO will be free not only from absorption of the Earth's atmosphere but from the thermal emission of the background, the sensitivity in the infrared can be much increased as compared with observations from the ground. The purpose of this International Scientific Research Program is to clarify the formation of the primavel galaxies and stellar evolution in the formation phase sa well as in the latest stage with the use of highly efficient ISO satellite. As intense infrared radiation may be emitted by the dusts formed during the violent processes in the formation of primavel galaxies as well as of proto-stars and in the latest stage of stellar evolution, infared radiation is the best probe to clarify such violent phenomena in the Universe. We are proposing observational programs in three major fields noted above in the ISO's GURANTEED TIME observations.For these observations to be carried out as we expected, it is necessary first to optimize the observational parameters of our proposals and second to prepare for data reduction and analysis. For the first purpose, 7 members visited ESTEC of ESA to analyze the feasibility of our observing programs and to input the final observing parameters in the mission database of the ISO satelite. This is the important step to fix the details of observations with ISO and this step has been well cleared by the visits of these members. For the second purpose, 2 members visited ESTEC to discuss the details of data analysis at various stages of the ISO mission and other problems related to the international collaboration in observations with ISO.

欧洲航天局(欧空局)将于1995年秋季发射的红外空间观测站是空间中第一个真正的天文观测站，在红外波长下运行。由于ISO是完全冷却的，使用ISO的观测不仅不会受到地球大气的吸收，而且不会受到背景热发射的影响，因此与地面观测相比，红外的灵敏度可以大大提高。这一国际科学研究计划的目的是利用高效的ISO卫星，阐明原始星系的形成和恒星在形成阶段以及最新阶段的演化。由于在原始星系和原恒星的形成以及恒星演化的最新阶段，在剧烈过程中形成的尘埃可能会发出强烈的红外辐射，因此红外辐射是解释宇宙中此类剧烈现象的最佳探测器。我们在国际标准化组织的保证时间观测中提出了上述三个主要领域的观测计划。为了使这些观测如我们预期的那样进行，首先必须优化我们建议的观测参数，其次是为数据整理和分析做准备。为了第一个目的，7名成员访问了欧空局ESTEC，分析了我们的观测计划的可行性，并将最终的观测参数输入到ISO卫星任务数据库中。这是确定国际标准化组织意见细节的重要一步，这些成员的访问清楚地表明了这一步。为了第二个目的，2名成员访问了ESTEC，讨论了国际标准化组织任务不同阶段的数据分析细节，以及与国际标准化组织在观测方面的国际协作有关的其他问题。
