A 330 { 360 Ghz Spectral Survey of G34.3+0.15 Ii. Chemical Modelling

چکیده

We describe a detailed depth-and time-dependent model of the molecular cloud associated with the ultracompact H ii region G34.3+0.15. Previous work on observations of NH 3 and CS indicates that the molecular cloud has three distinct physical components:-an ul-tracompact hot core, a compact hot core and an extended halo. We have used 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 diierent chemistries occur-ing in each component and are compared with abundances derived from our recent spectral line survey of G34.3+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...

A 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...

Ghz Brightness Measurements of Uranus , Neptune , and Other Secondary Calibrators with Bolocam between 2003 and 2010

Bolocam began collecting science data in 2003 as the long-wavelength imaging camera at the Caltech Submillimeter Observatory. The planets, along with a handful of secondary calibrators, have been used to determine the flux calibration for all of the data collected with Bolocam. Uranus and Neptune stand out as the only two planets that are bright enough to be seen with high signal-to-noise in sh...

Analysis and Optimization of a DAR IMPATT Diode for 330 GHz

The analysis and optimization of the npvnp avalanche diode have been realized on basis of the nonlinear model and special optimization procedure. This type of the diode that was named as Double Avalanche Region (DAR) IMPATT diode includes two avalanche regions inside the diode. The phase delay which was produced by means of the two avalanche regions and the drift region v is sufficient to obtai...
