摘要
本文根据MSC星的IRAS 12,25,60和100 μm测光资料及8—22μm低分辨率光谱,并结合其近红外测光结果,可见光谱特征,主元素丰度比以及在恒星内部发生的物理化学过程,讨论了这些恒星可能存在的演化状态,指出其间可能存在M→S→C的演化序列,也有发生M星直接演化到C星的可能性.
The possible evolution phases of MSC stars are discussed in this paper. This is based on the IRAS, PSC and LRS data with the near infrared photometry, the spectral characteristics, the abundance ratio of main elements and the internal chemical-physical process. It is pointed out that both M→S→C and direct M→C evolution sequences are possible.
