HD 63021: Chromospheric Activity and Mass Transfer in a Close Binary
D. G. Whelan, S. D. Chojnowski, J. Labadie-Bartz +13
Prompted by X-ray detections from multiple surveys, we investigated the A-type star HD 63021 and found that it is a double-lined spectroscopic binary with highly variable emission…
The Role of Radiolysis in the Modelling of CHO Isomers and Dimethyl Ether in Cold Dark Clouds
Alec Paulive, Christopher N. Shingledecker, Eric Herbst
Complex organic molecules (COMs) have been detected in a variety of interstellar sources. The abundances of these COMs in warming sources can be explained by syntheses linked to in…
Cosmic ray tracks in astrophysical ices: Modeling with the Geant4-DNA Monte Carlo Toolkit
Christopher N. Shingledecker, Sebastien Incerti, Alexei Ivlev +4
Cosmic rays are ubiquitous in interstellar environments, and their bombardment of dust-grain ice mantles is a possible driver for the formation of complex, even prebiotic molecules…
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…
Detection of Interstellar HCNC and an Investigation of Isocyanopolyyne Chemistry under TMC-1 Conditions
Ci Xue, Eric R. Willis, Ryan A. Loomis +10
We report an astronomical detection of HCNC for the first time in the interstellar medium with the Green Bank Telescope toward the TMC-1 molecular cloud with a minimum signific…
Isomers in Interstellar Environments (I): The Case of Z- and E-Cyanomethanimine
Christopher N. Shingledecker, Germán Molpeceres, Víctor Rivilla +2
In this work, we present the results of our investigation into the chemistry of Z- and E-cyanomethanimine (HNCHCN), both of which are possible precursors to the nucleobase adenine.…
