| Abstract: |
Almost three decades ago, \citet{Mathys1990} demonstrated the importance of studying Ap
stars showing resolved Zeeman split Fe II 6147.7 and 6149.2 lines. Such Zeeman split lines
can be seen in stars whose projected rotational velocity is sufficiently small and
whose magnetic field is strong enough to exceed the rotational Doppler broadening.
Observations of resolved Zeeman split lines permit the diagnosis of the average of
the modulus of the magnetic field over the visible stellar hemisphere.
Although Zeeman splitting is not expected in faster rotating hot massive stars,
we have recently been discovering early B-type stars displaying magnetically split spectral lines. |
