| Abstract: |
In non-degenerate stars, magnetic fields are
detected and measured through the Zeeman effect
in stellar spectral lines, mainly using the
polarization properties of Zeeman splitting. Such
data may now be modelled amazingly accurately.
In white dwarf stars, fields may be measured using
spectral line methods up to ∼ 10 MG (∼ 1 kT). Above
this level one can also estimate the field from
continuum circular (and sometimes linear)
polarization, although we do not yet know how to
model these correctly. |
