使用气球载望远镜 (BICE) 获得了 ρ Ophiuchi 暗云的 [C II] 158 μm 线发射的详细地图。 [C II]发射延伸至整个云（8 pc×6 pc），表明云中的紫外线辐射不是局域性的而是普遍分布的。发射峰值对应于高度红化的 B2 V 星 HD 147889 的位置。 ρ 蛇夫座云中的 I [CII] /I bol 比值高于 O 型恒星的活跃恒星形成区，这表明 ρ 蛇夫座云中的气体加热效率更高
A detailed map of the [C II] 158 μm line emission from the ρ Ophiuchi dark cloud has been obtained using a balloon-borne telescope (BICE). The [C II] emission is extended throughout the cloud (8 pc×6 pc), indicating that UV radiation in the cloud is not localized but is ubiquitously distributed. The peak of the emission corresponds to the position of the highly reddened B2 V star HD 147889. The ratio I [CII] /I bol in the ρ Ophiuchi cloud is higher than those found in active star-forming regions with O-type stars, which indicates a higher gas heating efficiency in the ρ Ophiuchi cloud
