Millimeter and Radio Interferometry of Herbig Ae/Be Stars

摘要

Nine Herbig Ae/Be stars have been observed at λ= 2.7 mm with the IRAM and BIMA interferome- ters in order to place constraints on the presence of disk material around these objects. Only one Herbig Ae/Be star, Elias 3-1, was detected with certainty; two additional stars, MWC 137 and V645 Cyg, were possibly detected. The remaining six Herbig Ae/Be stars were not detected. Two deeply embedded objects near the target stars, LkHα 198-MM and V1318 Cyg S, were also detected. The emission from Elias 3-1 and V1318 Cyg S is unresolved, while that from LkHα 198 MM is resolved.
