*Title:* Considerations on the morphology of coronal mass ejections

*Speaker:* Dr Hebe Cremades
Mendoza Group for Heliophysics Studies (GEHMe, University of Mendoza) and
CONICET
Argentina

*Abstract:*

Coronal mass ejections (CMEs) are undoubtedly the most spectacular
transient events that can be observed in the solar corona. Enabled by the
fleet of solar- and heliospheric-dedicated spacecraft with the capability
of detecting them remotely and/or in situ, CMEs and their interplanetary
counterparts have been characterized with increasing detail throughout the
years. Nevertheless, several aspects of CMEs remain elusive, including
their three-dimensional magnetic configuration, mainly due to limitations
inherent to remote-sensing and in situ observations. Still, they provide
valuable pieces of information that have high potential to shed light in
this respect. The study of CME morphology on the basis of remote-sensing
observations is an approach to that end, since it holds a close
relationship with the CME magnetic field configuration. Findings on CME
morphology are key for the interpretation and modeling of in situ
observations of these events at multiple spacecraft. In particular, the
extent of CMEs, expansion rates along orthogonal directions, departures
from the archetypical flux rope structure, and factors affecting the
characterization of CME morphology will be addressed.
