Interferometric mapping of magnetic fields: G30.79 FIR 10.

CORTES P. and CRUTCHER R.M.

Abstract (from CDS):

We present polarization maps of G30.79 FIR 10 (in W43) from thermal dust emission at 1.3 mm and from CO J=2⟶1 line emission. The observations were obtained using the Berkeley-Illinois-Maryland Association array in the period 2002-2004. The G30.79 FIR 10 region shows an ordered polarization pattern in dust emission, which suggests an hourglass shape for the magnetic field. Only marginal detections for line polarization were made from this region. Application of the Chandrasekhar-Fermi method yielded Bpos~1.7 mG and a statistically corrected mass to magnetic flux ratio λC~0.9, or essentially critical.
