WISE observations of visual carbon stars (VCSs), infrared carbon stars (IRCSs), extreme carbon stars (ECSs), J-type carbon stars JCSs), and silicate carbon stars (SCSs) are presented in this paper. We found that in the WISE observational region carbon stars still form a sequence of VCSs → IRCSs → ECSs with the color gradually increasing. We also found that in the WISE two-color diagrams the JCS distribution is similar to that for the VCS, while the ECS distribution is similar to the IRCS. In addition, most of these carbon stars are around or on the lower right side of blackbody distributions in the WISE two-color diagrams due to the thermal radiation from dusty circumstellar envelopes, while some of them are around or on the upper left side of power law distributions possibly due to the radiation from dusty disks or showing the influence from some molecular features.

对各种银河碳星的 WISE 观测

本文介绍了对可见碳星 (VCS)、红外碳星 (IRCS)、极端碳星 (ECS)、J 型碳星 (JCS) 和硅酸盐碳星 (SCS) 的 WISE 观测。我们发现在 WISE 观测区碳星仍然形成 VCSs→IRCSs→ECSs 的序列，颜色逐渐增加。我们还发现，在 WISE 双色图中，JCS 分布与 VCS 相似，而 ECS 分布与 IRCS 相似。此外，由于尘埃星周包层的热辐射，这些碳星中的大多数都在 WISE 双色图中黑体分布的右下方或附近，
