On the Inference of the Cosmic Ray Ionization Rate from the HCO-to-DCO Abundance Ratio: The Effect of Nuclear Spin
Christopher N. Shingledecker, Jennifer B. Bergner, Romane Le Gal +3
The chemistry of dense interstellar regions was analyzed using a time-dependent gas-grain astrochemical simulation and a new chemical network that incorporates deuterated chemistry…
Non-Detection of HCN toward TMC-1: Constraining the Chemistry of Large Carbon-Chain Molecules
Ryan A. Loomis, Christopher N. Shingledecker, Glen Langston +8
Bell et al. (1997) reported the first detection of the cyanopolyyne HCN toward the cold dark cloud TMC-1; no subsequent detections have been reported toward any source. Addi…
CSO and CARMA Observations of L1157. II. Chemical Complexity in the Shocked Outflow
Andrew M. Burkhardt, Niklaus M. Dollhopf, Joanna F. Corby +8
L1157, a molecular dark cloud with an embedded Class 0 protostar possessing a bipolar outflow, is an excellent source for studying shock chemistry, including grain-surface chemistr…
