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…
Infrared spectra of methane-containing ice mixtures for JWST data analyses
Varvara Karteyeva, Ruslan Nakibov, Igor Petrashkevich +2
Context. Solid methane (CH) is an important molecule in interstellar and planetary environments, serving as a precursor to complex organic compounds, and it is a potential bios…
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,…
Identification of solid N2O in interstellar ices using open JWST data
V. Karteyeva, R. Nakibov, I. Petrashkevich +2
Context. There are only six molecules containing N-O bond that are detected in gaseous phase in interstellar medium. One of those is nitrous oxide (N2O), which was searched for but…
Solid and Gaseous Methane in IRAS 23385+6053 as seen with Open JWST Data
Ruslan Nakibov, Varvara Karteyeva, Igor Petrashkevich +3
We present a new description of the 7.7~m region towards the high-mass star-forming region IRAS 23385+6053 taken from open James Webb Space Telescope Mid-Infrared Instrument Med…
Deuterium fractionation in cold dense cores in the low-mass star forming region L1688
I. V. Petrashkevich, A. F. Punanova, P. Caselli +5
In this work, we study deuterium fractionation in four starless cores in the low-mass star-forming region L1688 in the Ophiuchus molecular cloud. We study how the deuterium fractio…
