The DCN / HCN abundance ratio in hot molecular coresJ
We have observed the 3-2 transitions of DCN and HC 15 N in a number of hot molecular cores previously surveyed by us with the interesting result that the DCN/HCN ratio is low, a few times 10 ?3 , in the hot cores. The abundance ratio of DCN/HCN is derived bothòn-core' andòo-core' and, in general is larger at thèoo-core' positions. Comparision with chemical models of these sources indicates that...
متن کاملThe DCN / HCN abundance ratio in hot molecular cores
We have observed the 3-2 transitions of DCN and HC 15 N in a number of hot molecular cores previously surveyed by us with the interesting result that the DCN/HCN ratio is low, a few times 10 −3 , in the hot cores. The abundance ratio of DCN/HCN is derived both 'on-core' and 'off-core' and, in general is larger at the 'off-core' positions. Comparision with chemical models of these sources indica...
متن کاملHh Illumination of Clumps within Molecular Clouds
Molecular clouds are clumpy. Much of the clumpiness is unresolved by single-dish telescopes but is apparent in the data from array telescopes. Even in the unresolved observational data, the existence of clumpiness can be inferred from the distribution of molecular species. This evidence requires that “early-time” molecular species are widespread, while “late-time” species are more confined, and...
متن کاملHighly Variable Young Massive Stars in Atlasgal Clumps
High-amplitude variability in young stellar objects (YSOs) is usually associated with episodic accretion events. It has not been observed so far in massive YSOs. Here, the high-amplitude variable star sample of Contreras Peña et al. has been used to search for highly variable (ΔK 1 mag) sources coinciding with dense clumps mapped using the 850μm continuum emission by the ATLASGAL survey. A t...
متن کاملMolecular clumps in the W51 giant molecular cloud
In this paper, we present a catalogue of dense molecular clumps located within the W51 giant molecular cloud (GMC). This work is based on Heterodyne Array Receiver Programme 13CO J = 3–2 observations of the W51 GMC and uses the automated CLUMPFIND algorithm to decompose the region into a total of 1575 clumps of which 1130 are associated with the W51 GMC. We clearly see the distinct structures o...
