We have collected almost all B[e] stars (120 stars in total) listed in the literature up to the present time. We have then photometrically studied their infrared properties by using data from IRAS, WISE, and 2MASS. From several two-color diagrams we found that infrared radiation for the majority of B[e] stars shows a power law distribution from dusty/gaseous circumstellar disks in the 1–60 μm region. We also found that, possibly due to the influence of polycyclic aromatic hydrocarbon and silicate emissions, some B[e] stars have a blackbody distribution in the 3–12 μm region, and due to the influence of clouds/nebulae nearby some B[e] stars also show blackbody distributions in the IRAS wavelengths. Furthermore, we compared infrared properties between B[e] stars and Be stars, and between B[e] stars and HAeBe stars. We show that the infrared excess of B[e] stars is much larger than for Be stars in the 1–25 μm region, while both B[e] and HAeBe stars have similar infrared color properties in the 1–25 μm region.

B[e] 星在红外线中的新光度学研究

到目前为止，我们已经收集了文献中列出的几乎所有 B[e] 星（总共 120 颗星）。然后，我们使用来自 IRAS、WISE 和 2MASS 的数据对它们的红外特性进行了光度分析。从几张双色图中，我们发现大多数 B[e] 星的红外辐射在 1-60 μm 区域内显示出来自尘埃/气态环星盘的幂律分布。我们还发现，可能由于多环芳烃和硅酸盐排放的影响，一些B[e]星在3-12 μm区域有一个黑体分布，并且由于一些B[e]附近的云/星云的影响。 ] 恒星还显示 IRAS 波长中的黑体分布。此外，我们比较了 B[e] 星和 Be 星之间以及 B[e] 星和 HAeBe 星之间的红外特性。
