Mapping Observations of DNC and HNC in Dark Cloud Cores
We present results of mapping observations of the DNC, HNC, and HCO lines (J=1-0) toward 4 nearby dark cloud cores, TMC-1, L1512, L1544, and L63, along with observations of the DNC and HNC lines (J=21) toward selected positions. By use of statistical equilibrium calculations based on the LVG model, the H2 densities are derived to be (1.4-5.5)×10 5 cm, and the [DNC]/[HNC] ratios are derived to b...
متن کاملThe Shapes of Molecular Cloud Cores in Simulations and Observations
In this study, we investigate the shapes of starless and protostellar cores using hydrodynamic, self-gravitating adaptive mesh refinement simulations of turbulent molecular clouds. We simulate observations of these cores in dust emission, including realistic noise and telescope resolution, and compare to the observed core shapes measured in Orion by Nutter & Ward-Thompson (2007). The simulation...
متن کاملInfrared Dark Cloud Cores in the SCUBA Legacy Catalogue
We present an investigation of candidate Infrared Dark Cloud cores as identified by Simon et al. (2006) located within the SCUBA Legacy Catalogue. After applying a uniform noise cut to the Catalogue data we identify 154 Infrared Dark Cloud cores that were detected at 850μm and 51 cores that were not. We derive column densities for each core from their 8μm extinction and find that the IRDCs dete...
متن کاملDark Cloud Cores and Gravitational Decoupling from Turbulent Flows
We test the hypothesis that the starless cores may be gravitationally bound clouds supported largely by thermal pressure by comparing observed molecular line spectra to theoretical spectra produced by a simulation that includes hydrodynamics, radiative cooling, variable molecular abundance, and radiative transfer in a simple one-dimensional model. The results suggest that the starless cores can...
متن کاملDense Cores in Dark Clouds . XIV . N 2 H + ( 1 – 0 ) maps of dense cloud cores
We present results of an extensive mapping survey of N2H (1–0) in about 60 low mass cloud cores already mapped in the NH3(1,1) inversion transition line. The survey has been carried out at the FCRAO antenna with an angular resolution of 54, about 1.5 times finer than the previous ammonia observations made at the Haystack telescope. The comparison between N2H + and NH3 maps shows strong similari...
