Ubiquitous Aromatic Carbon Chemistry at the Earliest Stages of Star Formation
Andrew M. Burkhardt, Ryan A. Loomis, Christopher N. Shingledecker +4
Benzonitrile (-CHCN), a polar proxy for benzene (-CH}), has the potential to serve as a highly convenient radio probe for aromatic chemistry, provided this ri…
Interstellar Detection of the Highly Polar Five-Membered Ring Cyanocyclopentadiene
Michael C. McCarthy, Kin Long Kelvin Lee, Ryan A. Loomis +10
Much like six-membered rings, five-membered rings are ubiquitous in organic chemistry, frequently serving as the building blocks for larger molecules, including many of biochemical…
An Investigation of Spectral Line Stacking Techniques and Application to the Detection of HCN
Ryan A. Loomis, Andrew M. Burkhardt, Christopher N. Shingledecker +10
As the inventory of interstellar molecules continues to grow, the gulf between small species, whose individual rotational lines can be observed with radio telescopes, and large one…
Efficient Production of S in Interstellar Ices: The effects of cosmic ray-driven radiation chemistry and non-diffusive bulk reactions
Christopher N. Shingledecker, Thanja Lamberts, Jacob C. Laas +4
In this work, we reexamine sulfur chemistry occurring on and in the ice mantles of interstellar dust grains, and report the effects of two new modifications to standard astrochemic…
On Simulating the Proton-Irradiation of O and HO Ices Using Astrochemical-type Models, with Implications for Bulk Reactivity
Christopher N. Shingledecker, Anton Vasyunin, Eric Herbst +1
Many astrochemical models today explicitly consider the species that comprise the bulk of interstellar dust grain ice-mantles separately from those in the top few monolayers. Bomba…
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…
