A new submillimeter Class I methanol maser at 345.903 GHz near the massive protostar S255IR NIRS3
We present results of further investigation of radio emission from the remarkable molecular core S255IR-SMA1 harboring a \(\sim\) 20 Msun young stellar object NIRS3 which exhibited a disk-mediated accretion burst in 2015. Our study is based on observations of this object with ALMA in Band 7 with the longest baselines,...
