Resumen:
Coronal ejective events, in particular coronal mass ejections (CMEs),
expel mass and mag-netic field from the Sun into the interplanetary
medium. Interplanetary coronal mass ejections (ICMEs), a subset of which
are known as magnetic clouds (MCs), are considered to be the
interplanetary counterparts of CMEs. In general, the association between
these phenomena is determined taking into account the CME source region
position on the Sun, the time de-lay expected between both events,
and/or by comparing the orientation of the coronal and interplanetary
"in situ" magnetic fields. Several recent studies have shown this
connection in a more quantitative way, combining multi-wavelength remote
sensing and "in situ" observa-tions, together with magnetic field
modeling in both domains. This link is based, in general, in the
computation and comparison of magneto-hydrodynamic invariants, such as
magnetic fluxes and helicity. We will review the trends found in these
later studies and will discuss how this kind of analysis can help us to
constrain our modeling, both at the coronal level and in the
interplanetary space.
