Abstract
The results of a study of maser emission in the lines OH 1665 and 1667 MHz in the W51M star formation region are presented. The observations were carried out in 2022 and 2024 at the Large Radio Telescope in Nancay (France). The results of a study of the evolution of the flux density and the degree of circular polarization of individual spectral features are presented. Spatial identification of spectral features is carried out. It was found that the degree of linear polarization m of the five strongest features (55.92, 57.18, 57.72, 58.27 and 59.5 km/s) in the 1665 MHz line does not exceed 5%. The vector of the transverse magnetic field for these features is oriented within the angle 19.6° – 39.2°. Thus, it can be assumed that there is a spatially organized large-scale magnetic field in W51M (e1 and e2).
