Structure of the Magnetic Field in the W3 Core
Abstract
The Zeeman effect has been mapped in the H I absorption line toward the W3 core with approxinately 1-arcsec resolution. The line-of-sight component of the magnetic field exceeds 100 microG and reverses direction. This morphology could be the result either of the collapse of the molecular cloud during the star formation process or of the action of an expanding H II region on the placental molecular gas.
