摘要
本文根据对RAFGL595和RAFGL 954的近红外光谱观测,确定了它们的中心星也是富碳的。考虑到它们的光学对应体极弱,CO观测具有高的质量流失率.因此它们是光学厚的碳星.
Based on our near infrared low resolution spectroscopic observation of RAFGL 595 and RAFGL 954 using CVF spectrophotometer attached on the 1.26m IR telescope of Beijing Astronomical Observatory at Xinglong Station, we confirmed that their central stars are carbon-rich. According to the CO observation, the mass loss rate from RAFGL 595 is quite high and chis coincides with the fact that in POSS 'O' plate its optical counterpart can not be found. The situation of RAFGL 954 is similar to RAFGL 595. We confirm that both RAFGL 595 and RAFGL 954 arc optical thick carbon stars.
