| Abstract: |
This work reviews
our understanding of the magnetic fields
observed in the quiet Sun. The subject has undergone a major change
during the last decade (quiet revolution), and it will
remain changing since the techniques of diagnostic employed
so far are known to be severely biased. Keeping these
caveats in mind, our work covers the main observational
properties of the quiet Sun magnetic fields:
magnetic field strengths, unsigned magnetic
flux densities, magnetic field inclinations, as well as the temporal
evolution on short time-scales (loop emergence), and long time-scales
(solar cycle). We also summarize the main theoretical ideas
put forward to explain the origin of the quiet Sun magnetism.
A final prospective section points out various areas of
solar physics where the quiet Sun magnetism
may have an important physical role to play
(chromospheric and coronal structure,
solar wind acceleration, and
solar elemental abundances). |
