The Model Magnetic Configuration of the Extended Corona in the Solar Wind Formation Region
Igor Veselovsky, Olga Panasenco
The coupling between small and large scale structures and processes on the Sun and in the heliosphere is important in the relation to the global magnetic configuration. Thin helios…
The Build-up to Eruptive Solar Events Viewed as the Development of Chiral Systems
Sara F. Martin, Olga Panasenco, Mitchell A. Berger +4
When we examine the chirality or observed handedness of the chromospheric and coronal structures involved in the long-term build-up to eruptive events, we find that they evolve in…
Coronal Pseudostreamers: Source of Fast or Slow Solar Wind?
Olga Panasenco, Marco Velli
We discuss observations of pseudostreamers and their 3D magnetic configuration as reconstructed with potential field source surface (PFSS) models to study their contribution to the…
Origins of Rolling, Twisting and Non-Radial Propagation of Eruptive Solar Events
Olga Panasenco, Sara F. Martin, Marco Velli +1
We demonstrate that major asymmetries in erupting filaments and CMEs, namely major twists and non-radial motions are typically related to the larger-scale ambient environment aroun…
2010 August 1-2 sympathetic eruptions: I. Magnetic topology of the source-surface background field
V. S. Titov, Z. Mikic, T. Török +2
A sequence of apparently coupled eruptions was observed on 2010 August 1-2 by SDO and STEREO. The eruptions were closely synchronized with one another, even though some of them occ…
