About this Research Topic
The advent of the Parker Solar Probe and the Solar Orbiter missions is already imposing new constraints in both the modeling and computer simulation efforts of dynamic solar phenomena aimed at shedding light onto the physical processes at work during their origin and evolution. For instance, white-light imaging data acquired from short heliocentric distances allows, in certain cases, the imaging “in-situ” of coronal features. These novel observations are already challenging existing models and theories, and hence demand not only the use of multi view-point observations but also the synergy provided by joint in-situ measurements and remote-sensing observations to narrow the field of possible interpretations.
The development of coronal events during the first few solar radii are undoubtedly decisive for their subsequent evolution, but at the same time are the key for understanding the processes involved in their genesis and onset. In spite of the vast efforts carried out to date, numerous open questions remain on their formation, triggering, and evolution. Moreover, the characterization of the coronal environment during the early stage of coronal transients is crucial to characterize both the morphology and early kinematics of the events, and hence understand, e.g., the production and release of solar energetic particles (if any). Recent unprecedented missions like Parker Solar Probe and Solar Orbiter, in combination with existing solar and heliospheric observatories, enable synergistic multi-disciplinary analyses of coronal transients from multiple vantage points. The plethora of available data sets and the unanswered questions demand a renewed characterization of the early development and evolution at short heliocentric distances of coronal transients and their environment, that in turn will result in the necessary addition of complexity to models and assumptions.
We solicit a series of reviews and articles with the objective of giving an overview of new challenges and results (theoretical, observational, numerical and instrumental) that have opened up for solar physics from the latest generation of data provided by space-borne instrumentation. The scope of this Frontiers Research Topic could include not only coronal mass ejections but also the transients that might be related to such phenomena. Contributions will consider the analysis of remote sensing and in-situ observations of the solar atmosphere within 0.5 AU. Interdisciplinary research efforts combining single- or multi-viewpoint observations with theory and/or modeling are particularly welcome.
