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…
Identifying Evolutionary Stages of Molecular Clumps through Unsupervised and Supervised Machine Learning
K. V. Plakitina, M. S. Kirsanova, A. B. Ostrovskii +3
The evolutionary classification of molecular clumps, crucial for understanding star formation, is commonly based on human-assigned categories derived from infrared (IR) emission an…
MOLLId: software for automatic identification of spectral molecular lines in the sub-millimeter and millimeter bands and its application to the spectra of protostars from the region RCW 120
A. A. Farafontova, M. S. Kirsanova, S. V. Salii
In this work, we present the program MOLLId (MOLecular Line Identification) for automated molecular lines approximation with gaussian profile. Molecular identification was performe…
Submillimeter Class II methanol masers near the massive protostar S255IR NIRS3: evolution and excitation of the A series and a new maser line at 345.919 GHz
I. I. Zinchenko, S. V. Salii, A. M. Sobolev +3
We present the results of the further investigation of the Class II methanol maser emission in the A transition at 349.1 GHz discovered in 2016 in the remarkab…
