我们绘制了450 μm和850 μm的南冠状体图谱。我们将这些地图与之前对该地区的调查进行了比较,并对云中心的原恒星源以前未知的性质提供了新的了解。我们澄清了以前在低分辨率数据中发现的两毫米源的性质。我们发现了一颗新的0级原恒星,我们将其标记为SMM 1B,我们测量了一些更进化的原恒星的包层质量。我们发现了两个新的前恒星核,我们称之为SMM 1A和SMM 6。
We present 450- and 850-μm maps of R Coronae Australis. We compare the maps with previous surveys of the region, and shed new light on the previously unknown nature of the protostellar sources at the centre of the cloud. We clarify the nature of two millimetre sources previously discovered in lower-resolution data. We identify one new Class 0 protostar, which we label SMM 1B, and we measure the envelope masses of a number of more evolved protostars. We identify two new pre-stellar cores, which we call SMM 1A and SMM 6.
