某些小博克球的距离估计
Distance estimation of some selected small Bok globules
摘要：
小博克球的距离测定往往是困难的，因为它的尺寸小，不透明。在这项工作中，我们使用近红外测光（2 MASS $JHK_S$颜色）来确定六个小博克球CB 17，CB 24，CB 188，CB 224，CB 230和CB 240的距离。到这些云的距离估计分别为$478 \pm 88$、$293 \pm 54$、$262 \pm 49$、$378 \pm 70$、$293 \pm 54$和$429 \pm 79$秒差距。
英文摘要：
The distance determination of small Bok globules is often difficult because of its small size and opaqueness. In this work, we determine the distances to six small Bok globules CB 17, CB 24, CB 188, CB 224, CB 230 and CB 240 using near infra red photometry (2MASS $JHK_S$ colors). The distances to these clouds are estimated to be $478 \pm 88$, $293 \pm 54$, $262 \pm 49$, $378 \pm 70$, $293 \pm 54$ and $429 \pm 79$ parsec respectively.
