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…

Submillimeter Class II methanol masers near the massive protostar S255IR NIRS3: evolution and excitation of the $J_{1} - J_{0}$ 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 $1 4_{1} - 1 4_{0}$ A $^{-+}$ transition at 349.1 GHz discovered in 2016 in the remarkab…
