[65.07] Radio Diagnostics of Magnetic Fields in CMEs

T. S. Bastian (National Radio Astronomy Observatory)

A variety of remote sensing techniques are available at radio wavelengths for measuring or constraining the magnetic field in CMEs in the corona and inner heliosphere. Some have been exploited; for others the ``proof of concept" has been established; still others are purely speculative at this point and rely on the development of future instrumentation. They can be grouped into three distinct classes: 1) radio emission intrinsic to CMEs (synchrotron emission); 2) Faraday rotation of background radio sources viewed through CMEs; 3) studies of radio bursts associated with CMEs (type II, SA type III, and type IV).

This talk will review the specific techniques available in each of these classes and describe what they can tell us about magnetic fields in CMEs. The requirements on instrumentation required to exploit these techniques will be emphasized.
