摘要
介绍了有关星际26A1发射的1.809MeVγ射线的空间探测结果。简要介绍并评述了有关星际26A1天体来源问题中的平稳核燃烧星体模型,即大质量主序星模型、WR星模型和处于渐近巨分支阶段(AGB)红巨星模型。根据近几年核物理实验新进展所获得的有关核反应率的新数据,指出这些模型都面临着严重困难,似乎不大可能成为星际26A1的重要天体源泉。
The results of 1.809 MeV ray emited by the interstellar 26A1 from the space observationis presented in this paper. The stable nuclear burning star models, i.e., the model ofmassive main-sequence stars, WR star model and the model of red- giant in the stage ofasymptotic giant branch, are briefly reviewed. Based on the data of nuclear reaction ratederived by the progress in the nuclear experiment in recent years, it is pointed out thatall these models might fail to provide the important astrophysical sources of interstellar26A1 as there are some severe difficulties.
