Clouds, Clumps, Cores & Comets - a Cosmic Chemical Connection?
S. B. Charnley, S. D. Rodgers
We discuss the connection between the chemistry of dense interstellar clouds and those characteristics of cometary matter that could be remnants of it. The chemical evolution obser…
Nitrogen superfractionation in dense cloud cores
S. D. Rodgers, S. B. Charnley
We report new calculations of interstellar 15N fractionation. Previously, we have shown that large enhancements of 15N/14N can occur in cold, dense gas where CO is frozen out, but…
Hydrogen Isocyanide in Comet 73P/Schwassmann-Wachmann (Fragment B)
D. C. Lis, D. Bockelee-Morvan, J. Boissier +3
We present a sensitive 3-sigma upper limit of 1.1% for the HNC/HCN abundance ratio in comet 73P/Schwassmann-Wachmann (Fragment B), obtained on May 10-11, 2006 using Caltech Submill…
Chemical chronology of the Southern Coalsack
S. D. Rodgers, S. B. Charnley, R. G. Smith +1
We demonstrate how the observed H2O ice column densities toward three dense globules in the Southern Coalsack could be used to constrain the ages of these sources. We derive ages o…
Observations of chemical differentiation in clumpy molecular clouds
J. V. Buckle, S. D. Rodgers, E. S. Wirström +4
We have extensively mapped a sample of dense molecular clouds (L1512, TMC-1C, L1262, Per 7, L1389, L1251E) in lines of HC3N, CH3OH, SO and C^{18}O. We demonstrate that a high degre…
Organic Molecules in the Hot Corinos and Circumstellar Disks of IRAS 16293-2422
H. -C. Huang, Y. -J. Kuan, S. B. Charnley +3
Using the recently-commissioned Submillimeter Array (SMA), we have detected several complex organic molecules, including (CH3)2O, C2H5OH, C2H5CN, and tentatively CH2CDCN, toward th…
