Presentation #207.03 in the session Star Formation Near and Far.
We present Karl G. Jansky Very Large Array (VLA) Zeeman effect observations in the 38 GHz Class II methanol maser line toward the high mass star forming region NGC 6334F. Millimeter sources observed in this region indicate that it is at a very early stage of star formation. Class II methanol masers occur close to the protostar. The Zeeman effect has been detected in the 6.7 GHz Class II methanol line toward several star forming regions, but the ability to observe it in the 38 GHz line opens a new window into the observation of magnetic fields in star forming regions. We detect fields of the order of tens of Hz at 3-6 σ levels in multiple Gaussian components fitted to the observed profiles. If the Zeeman splitting factor for these lines is of the order of 1 Hz/mG as calculated for some other well-known methanol maser lines, then our observations indicate fields of the order of tens of mG in these regions. Such fields likely play an important role in the star formation process.
