Observations 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 کاملPopulations of Young Stellar Objects in Nearby Molecular Clouds
We develop a new method to identify YSOs from star-forming regions using the photometry data from Spitzer’s c2d Legacy Project. The aim is to obtain YSO lists as complete as possible for studying the statistical properties, such as Star Formation Rate (SFR) and lifetimes of YSOs in different evolutionary stages. The largest obstacle for identifying YSOs comes from background galaxies with simil...
متن کاملAmmonia observations of the nearby molecular cloud MBM 12
We present NH3(1,1) and (2,2) observations of MBM 12, the closest known molecular cloud (65 pc distance), aimed to find evidence for on-going star formation processes. No local temperature (with a Trot upper limit of 12 K) nor linewidth enhancement is found, which suggests that the area of the cloud we mapped (∼ 15 size) is not currently forming stars. Therefore, this close “starless” molecular...
متن کاملSWS 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 کاملObservations of chemical differentiation in clumpy molecular clouds.
We have extensively mapped a sample of dense molecular clouds (L1512, TMC-1C, L1262, Per7, L1389, L1251E) in lines of HC3N, CH3OH, SO and C18O. We demonstrate that a high degree of chemical differentiation is present in all of the observed clouds. We analyse the molecular maps for each cloud, demonstrating a systematic chemical differentiation across the sample, which we relate to the evolution...
