COJ = 2 → 1 observations of the nearby galaxies Dwingeloo
We present an exploratory survey of the central regions of the nearby spiral galaxies Dwingeloo 1 and Dwingeloo 2 made in the CO J = 2→1 line at 230 GHz using the James Clerk Maxwell Telescope. In Dwingeloo 1, which is probably the nearest grand-design barred spiral, the CO emission was sampled along a cross with its major axis aligned with the bar. The CO emission is an order of magnitude weak...

متن کاملThe circumstellar envelope of π 1 Gru
CO(J = 2–1) and SiO(J = 5–4) emission has been observed from the molecular envelope around the nearby S star π1 Gru. The CO line profile differs from the usual parabolic shape seen in uniformly-expanding envelopes; it has a Voigtlike profile and two horns. A model for line formation in the envelope shows that a tilted, expanding disk reproduces the observations well. The star also has a fast mo...

15 صفحه اولThe circumstellar molecular envelope of HD 101584
CO radio line observations reveal a molecular gas envelope around the peculiar star HD101584 with characteristics very similar to those of wellknown young post-AGB objects. We estimate that there is at least 0.1 M of molecular gas, very likely remnant gas from a former AGB-envelope. This gas has been efficiently accelerated to very high velocities (>50 km s−1, and a significant fraction to >100...
