Multiline observations of S255IR with ALMA

Abstract

We present preliminary results of the high resolution $(0.10^{\prime \prime }\times 0.15^{\prime \prime })$ observations of the high mass star forming region S255IR with ALMA in several spectral windows from ~ 335 GHz to ~ 350 GHz. The main target lines were C${}^{34}$S(7-6), CH${}_3$CN($19_K-18_K$), CO(3-2) and SiO(8-7), however many other lines of various molecules have been detected, too. We present sample spectra and maps, discuss briefly the source structure and kinematics. A new, never predicted methanol maser line has been discovered.
