摘要
IRAS04000+5052的光学对应体在POSS的E片上是一个展源.我们利用北京天文台2.16m望远镜加红敏CCD系统对此源进行了VRI波段的观测,发现其R波段图像有明显的延伸,且辐射远强于Ⅴ、Ⅰ波段.用北台1.26m红外望远镜对此源的红外监测结果表明它有较大的近红外光变.根据IRAS流量值和LRS谱,以及其形态特征,我们判断它可能是一个被HII区所包围着的正在形成恒星的年轻天体.
Using 2.16m telescope with CCD system at Xinglong Station, Beijing Astronomical Observatory, IRAS 04000+5052 has been observed at VRI bands respectively. The R-filter image of the source shows very distinct extension feature. Radiation of the source at R band is much stronger than that at V and I bands. By using the 1.26m infrared telescope, a large variation at near infrared bands was also found. From the IRAS fluxes and LRS spectrum, as well as the morphology of the source, we conclude that k may possibly be a young object in the process forming new
