SWS observations of solid CO2 in molecular clouds
We report absorption features of solid CO2 stretching and bending modes in several lines of sight, including embedded young stellar objects and the Galactic Center source Sgr A*. The overall CO2 abundance in ices is 15% relative to H2O. Profile shapes are consistent with the presence of grain mantles with distinct polar (H2O-rich) and nonpolar (CO or CO2-rich) layers. In addition to the normal ...
متن کاملWhat Determines the Typical Mass of Dense Cores in Quiescent, Nonmagnetized Molecular Clouds?
By means of one-dimensional simulations, we study the collapse of a quiescent, nonmagnetized lamentary molecular cloud, taking into account the heating and cooling processes. At the initial state, the model cloud has the central density of 10 3 cm ?3 and temperature of 15 K. We follow its contraction until the central density reaches to 10 10 cm ?3. The cloud contracts mainly due to the CO line...
متن کاملObservations of in Dense Molecular Clouds
has been detected using infrared absorption spectroscopy along the lines of sight to six infrared 3 sources in dense molecular clouds : AFGL 2136, W33A, Mon R2 IRS 3, AFGL 961E, AFGL 2591, and AFGL 490. Upper limits to the column densities of are reported for an additional nine sources. The 3 column densities of CO toward Mon R2 IRS 3 and AFGL 961E have been determined from observations of the ...
متن کاملChemistry in Dense Molecular Clouds: Theory and Observational Constraints
For the most part, gas phase models of the chemistry of dense molecular clouds predict the abundances of simple species rather well. However, for larger molecules and even for small systems rich in carbon these models often fail spectacularly. We present a brief review of the basic assumptions and results of large scale modeling of the chemistry in dense molecular clouds. Particular attention w...
متن کاملChlorine in Dense Interstellar Clouds: the Abundance
We report the first detection of a chlorine-bearing molecular species in the interstellar medium via emission from the J = 1----> 0 transition of HCl at 625.9 GHz toward OMC-1. The relative strengths, widths, and velocities of the resolved hyperfine components are consistent with moderate optical depth emission originating from dense, quiescent molecular cloud material (VLsR = 9 km s1). The ove...
