We present deep near-infrared (NIR) imaging of Sh 2-209 (S209), a low-metallicity ([O/H]=-0.5dex) HII region in the Galaxy. From the NIR images, combined with astrometric data...
我们报道了沙普利斯2-209(Sh 2-209,简称S209)的深场近红外(near-infrared, NIR)成像结果,该天体是银河系内一处氧丰度相对太阳低0.5 dex的低金属丰度电离氢区(HII region)。基于该近红外图像并结合天体测量数据
