متن کاملResetting chemical clocks of hot cores based on S-bearing molecules
We report a theoretical study of sulphur chemistry, as applied to hot cores, where S-bearing molecular ratios have been previously proposed and used as chemical clocks. As in previous models, we follow the S-bearing molecular composition after the injection of grain mantle components into the gas phase. For this study, we developed a time-dependent chemical model with up-to-date reaction rate c...
متن کاملChemical Models of Hot Molecular Cores
We present the results of observational studies of a number of molecular clouds associated with ultracompact HII regions in regions of massive star formation. We derive molecular abundances and show that gas-phase-only chemical models of these regions are incapable of reproducing the observations. It appears that a rich chemistry occurs in the ice matrices frozen onto dust grains at high densit...
متن کاملSulphur chemistry and evolution in hot cores
We compare the results of our JCMT spectral line survey of molecular gas towards ultracompact Hii regions with the predictions of models of sulphur chemistry in hot cores. We investigate the range of evolutionary models that are consistent with the observed physical conditions and chemical abundances, and see to what extent it is possible to constrain core ages by comparing abundances with the ...
متن کاملCyanopolyynes and sulphur bearing species in hot cores: Chemical and line excitation models
We present results from a time dependent gas phase chemical model of a hot core based on the physical conditions of G305.2+0.2. While the cyanopolyyne HC3N has been observed in hot cores, the longer chained species, HC5N, HC7N, and HC9N have not been considered typical hot core species. We present results which show that these species can be formed under hot core conditions. We discuss the impo...
