The Hanle effect and the determination of magnetic fields

Résumé

The determination of prominence magnetic fields by interpreting the two measured parameters that describe the linear polarization of spectral lines (the Hanle method) is discussed. The possibility of determining the three components of a prominence magnetic field by using simultaneous observations in two different lines is considered. Limitations on the Hanle method are summarized. It is shown that a complete determination of a prominence magnetic field may be possible with the Hanle method by observing the prominence of interest during rotation of the sun.
