Description

Zeeman splitting observed from maser line profiles, enables the line-of-sight magnetic field magnitude to be ascertained. And the maser’s linear polarization position angle provides the magnetic field orientation in the reference-frame perpendicular to the observer. This detail, together with changing maser linear and circular polarization, has facilitated the creation of model where we are able to describe the magnitude, orientation and variation of the magnetic field impacting the masering region. The presentation will describe the observed polarization, the model and the inferred magnetic field. How the magnetic field relates to known and generally assumed magnetic field properties of star-forming regions will be discussed.
