The Magnetic Field

AbstractThe role of magnetic field in late type stars such as proto-planetary and planetary nebulae (PPNe/PNe), is poorly known from an observational point of view. We present submillimetric observations realized with the Submillimeter Array (SMA) which unveil the dust continuum polarization in the envelopes of two well known PPNe: CRL 618 and OH 231.8+4.2. Assuming the current grain alignment theory, we were then able to trace the geometry of the magnetic field.

Ambient Magnetic Field

A review of the methods of determining magnetic field parameters in astrophysical situations is presented. The role of radio observations is only briefly discussed because of recent review coverage, but a more detailed description is given of the optical and infrared polarisation produced by aligned dust grains, with particular reference to the relation between the grain alignment direction and the ambient magnetic field. Some recent results are outlined.
