Resumen:
Coronal
ejective events, in particular coronal mass ejections (CMEs),
expel mass and magnetic field from the Sun into the interplanetary
medium.
An important subset of these transient interplanetary CMEs
are known as magnetic clouds. These huge plasmoids are characterized by
a strongly enhanced magnetic field intensity (with respect to ambient
values), a smooth and large coherent rotation of the magnetic field
vector, and a low proton temperature. Several studies have shown the
connection between magnetic clouds
and their coronal source regions by a combined analysis of multi-wavelength
remote sensing and in situ observations, together with magnetic field
modeling. This link is based, in general, in the computation and comparison
of magneto-hydrodynamic invariants in both domains. We will discuss how this kind of
analysis can be used to constrain models,
both at the coronal level and in the interplanetary space.
