چکیده
We describe a detailed depthand time-dependent model of the molecular cloud associated with the ultracompact H ii region G 34.3+0.15. Previous work on observations of NH3 and CS indicates that themolecular cloud has three distinct physical components:an ultracompact hot core, a compact hot core and an extendedhalo.Wehaveused the physical parameters derived from these observations as input to our detailed chemical kinetic modelling. The results of the model calculations are discussed with reference to the different chemistries occuring in each component and are compared with abundances derived from our recent spectral line survey of G 34.3+0.15 (Paper I).

A 330 – 360 GHz spectral survey of G 34 . 3 + 0 . 15 III . The outer halo
We have undertaken a 330–360 GHz molecular line survey of the halo gas surrounding the hot core associated with G34.26+0.15. In contrast to our molecular line survey of the hot core itself, where 338 lines from at least 38 species were detected, only 18 lines from 9 species were detected in the halo. The lines are mainly single transitions of simple di-atomic and triatomic molecules. Lower limi...

متن کاملA molecular line survey of the candidate massive Class 0
We have carried out a molecular line survey of the candidate massive protostar IRAS 23385+6053, covering a 27.2 GHz frequency range in the 330–360 GHz atmospheric window. We detected 27 lines originating from a total of 11 species. Over a third of the identified molecular lines are from the asymmetric top molecule methanol (CH3OH). We did not detect any emission from high-excitation lines or ty...
متن کاملA line survey of Orion KL from 325 to 360 GHz.
We present a high-sensitivity spectral line survey of the high-mass star-forming region Orion KL in the 325-360 GHz frequency band. The survey was conducted at the Caltech Submillimeter Observatory on Mauna Kea, Hawaii. The sensitivity achieved is typically 0.1-0.5 K and is limited mostly by the sideband separation method utilized. We find 717 resolvable features consisting of 1004 lines, among...
