Mapping Interstellar Ice Inventory toward Class 0 Protostars in Star-forming Region Orion A with JWST Data
Igor Petrashkevich, Yaroslav Pavlyuchenkov, Anna Punanova +7
We present a detailed study of the spatial distribution and chemical composition of interstellar ices toward six Class 0 protostars (HOPS-56, HOPS-60, HOPS-73, HOPS-91, HOPS-96, an…
Complex organic molecules and cosmic ray ionisation rate towards the massive protostar Cepheus A HW2
Emma W. Nielsen, Anna Punanova, Eva Wirström +5
Cosmic rays (CRs) are important drivers for molecular chemistry in star-forming regions, and laboratory experiments have shown that CRs can stimulate the release of complex organic…
Deuterium fractionation and CO depletion in Barnard 5
Igor Petrashkevich, Anna Punanova, Paola Caselli +3
Deuterium fractionation provides a key diagnostic of the physical and chemical evolution of prestellar and protostellar cores, where it is strongly linked to CO depletion in cold,…
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…
Off-lattice Microscopic Monte Carlo Modeling of Molecular Hydrogen Formation on Carbonaceous Dust Grains
N. A. Satonkin, A. B. Ostrovskii, A. A. Mozhegorov +2
In this work, we present an off-lattice Monte Carlo model of accretion and migration of hydrogen atoms on a rough surface of carbon dust grain. The migration of physisorbed atoms b…
Formation of Complex Organic Molecules in Prestellar Cores: The Role of Non-Diffusive Grain Chemistry
Katerina Borshcheva, Gleb Fedoseev, Anna F. Punanova +3
We present the results of astrochemical modeling of complex organic molecules (COMs) in the ice and gas of the prestellar core L1544 with the recently updated MONACO rate equations…
