The Analysis of ISO SWS Spectra and the Studies of Molecular and Dust Features for 29 SiC Carbon Stars

本文给出了银河系12颗碳星的J、H、K波段的测光结果，并讨论了星际红化的影响。

The infrared photometry in J , H and K bands for 12 carbon stars in Our Galaxy are given in this paper , while the effect of interstellar reddening are discussed .

碳星是中等质量星演化到AGB阶段时可能形成的一种恒星，它由氧星演化而来，[C／O]＞1。

Carbon stars with C / O > 1 are a kind of stars that form at the AGB stage and evolved from oxygen-rich AGB stars with mid-mass .

IRAS17213&3841作为富碳星列于新版碳星星表中。

IRAS 17213-3841 is listed as a carbon star in the new carbon star catalog .

极端碳星是高度演化后的红外碳星，它的质量损失率及光深都非常高，几乎没有其光学对应体，并将很快演化为前行星状星云。

The extreme carbon stars , whose derived mass loss rates and optical depths are both very high , are more evolved than infrared carbon stars .

红外碳星经历了重要的质量损失过程，是光学碳星演化的后期。

These stars are undergoing important mass loss process and are likely to represent a more evolved phase of the stellar evolution than visual carbon stars .

本文主要致力于研究富碳AGB星的ISOSWS红外光谱的演化和它的分子、尘埃特征。

This present paper is contributed to the study of the evolutionary nature of ISO SWS spectra from carbon-rich AGB stars ( carbon stars ) and molecular and dust features around such carbon stars .

这些模型是依据氦或碳和氧构成星核，部分地或全部地产生瞬时完成的核燃烧。

Comparison is made to recent observations . The models are based on the instantaneous partial or total thermonuclear burning of a degenerate carbon / oxygen / helium core .
