| 摘 要： | 本文以369个在四个波段上都被探测到了的IRAS亮星系为依据,讨论了星系的IRAS颜色。根据IRAS颜色对它们做了分类,用简单的双黑体模型,可以很好拟合绝大多数IRAS亮星系的辐射。

| Abstract: | Based on a sample of 369 galaxies which are detected by IRAS in all four bands, the colors of IRAS galaxies are discussed in this paper. By their colors, they could be classified into four groups, i.e. normal, starburst, AGN and normal + peculiar. The colors at short wavebands are sensitive for the classification. A simple model of two black body components could be used to fit IRAS emission of galaxies well. |
