我们已经进行了高灵敏度的搜索，在连续的1.4和2.7毫米的IRAM干涉仪在高原德布尔的Herbig Be恒星周围的拱星盘。在这封信中，我们报告了三颗经过充分研究的B 0星的数据：MWC 1080，MWC 137和R Mon。后者也被观察到在连续0.7和1.3厘米使用NRAO甚大阵列。我们报告了在MWC 1080和R Mon周围探测到的拱星盘，质量分别为Md ~ 0.003和0.01 M，而对于MWC 137，我们估计盘质量上限为0.007 M。我们的研究结果表明，比值Md/M* 是至少一个数量级低Herbig Be星比Herbig Ae和金牛T星。
We have carried out a high-sensitivity search for circumstellar disks around Herbig Be stars in the continuum at 1.4 and 2.7 mm using the IRAM interferometer at the Plateau de Bure. In this Letter, we report data on three well-studied B0 stars: MWC 1080, MWC 137, and R Mon. The two latter have also been observed in the continuum at 0.7 and 1.3 cm using the NRAO Very Large Array. We report the detection of circumstellar disks around MWC 1080 and R Mon with masses of Md ~ 0.003 and 0.01 M☉, respectively, while for MWC 137 we estimate a disk mass upper limit of 0.007 M☉. Our results show that the ratio Md/M* is at least an order of magnitude lower in Herbig Be stars than in Herbig Ae and T Tauri stars.
