Descripción
Waves connect all the layers of the Sun, from its interior to the upper
atmosphere. It is becoming clear now the important role of magnetic
field on the wave propagation. Magnetic field modifies propagation speed
of waves, thus affecting the conclusions of helioseismological studies.
It can change the direction of the wave propagation, help channeling
them straight up to the corona, extending the dynamic and magnetic
couplings between all the layers. Modern instruments provide
measurements of complex patterns of oscillations in solar active regions
and of tiny effects such as temporal oscillations of the magnetic field.
The physics of oscillations in a variety of magnetic structures of the
Sun is similar to that of pulsations of stars that posses strong
magnetic fields, such as roAp stars. All these arguments point toward a
need of systematic self-consistent modeling of waves in magnetic
structures that is able to take into account the complexity of the
magnetic field configurations. In this paper, we describe simulations of
this kind, summarize our recent findings and bring together results from
the theory and observations.
