Inventories of Rich Carbon-Chain Chemistry in Prestellar and Starless Cores in the Perseus Molecular Cloud
Anissa Pokorny-Yadav, Samantha Scibelli, Judit Ferrer Asensio +3
Carbon-chain molecules serve as an important reservoir of reactive organic matter that will eventually be incorporated into protoplanetary disks, planets, and cometary material. Pr…
c-C3H2 deuteration towards prestellar and starless cores in the Perseus Molecular Cloud
J. Ferrer Asensio, S. Scibelli, L. Steffes +6
Deuterium fractionation becomes highly efficient in cold, dense cores where CO is frozen out. Cyclopropenylidene (c-C3H2), an early-formed carbon ring, and its deuterated isotopolo…
The Green Bank Ammonia Survey: Data Release 2
Jaime E. Pineda, Rachel K. Friesen, Erik Rosolowsky +22
We present an overview of the final data release (DR2) from the Green Bank Ammonia Survey (GAS). GAS is a Large Program at the Green Bank Telescope to map all Gould Belt star-formi…
Nascent chemical complexity in prestellar core IRAS 16293E: complex organics and deuterated methanol
Samantha Scibelli, Maria N. Drozdovskaya, Paola Caselli +5
Prestellar cores represent early sites of low-mass ( few M) star and planet formation and provide insight into initial chemical conditions of complex organic mole…
First Detections of PN, PO, and PO+ toward a Shocked Low-mass Starless Core
Samantha Scibelli, Andrés MegÃas, Izaskun Jiménez-Serra +6
Phosphorus is a key element that plays an essential role in biological processes important for living organisms on Earth. The origin and connection of phosphorus-bearing molecules…
The Young Ages of 70 μm-dark Clumps Inferred from Carbon Chain Chemistry
Kadin Worthen, Brian E. Svoboda, David S. Meier +4
The physical conditions of the earliest environment of high-mass star formation are currently poorly understood. To that end, we present observations of the carbon chain molecules…
