Investigation of the Two-Dimensional Velocity Field of the Large-Scale Coronal Wave from September 6, 2011 using the SOLERwave Tool
Markus Baumgartner-Steinleitner, Astrid M. Veronig, Karin Dissauer +1
We investigate the two-dimensional velocity field of the fast and complex large-scale coronal wave observed on September 6, 2011. We use both a classical perturbation profile appro…
Magnetic Topology and Loop Statistics in Observed Coronal Holes Using Potential Field Modeling
Stephan G. Heinemann, Jens Pomoell, Manuela Temmer
Potential Field Source Surface (PFSS) models are widely used to study the solar corona and form the basis for solar wind forecasting, yet often fail to reproduce observed propertie…
Turbulence-Driven Corrugation of Collisionless Fast-Magnetosonic Shocks
Immanuel Christopher Jebaraj, Mikhail Malkov, Nicolas Wijsen +4
Collisionless fast-magnetosonic shocks are often treated as smooth, planar boundaries, yet observations point to organized corrugation of the shock surface. A plausible driver is u…
Evaluating Solar Wind Forecast Using Magnetic Maps That Include Helioseismic Far-Side Information
Stephan G. Heinemann, Dan Yang, Shaela I. Jones +5
To model the structure and dynamics of the heliosphere well enough for high-quality forecasting, it is essential to accurately estimate the global solar magnetic field used as inne…
Effect of interplanetary shock waves on turbulence parameters
Emilia Kilpua, Simon Good, Juska Soljento +6
We have performed an extensive statistical investigation of how interplanetary fast forward shocks affect certain turbulence parameters, namely, the cross-helicity, , residua…
Quantifying Uncertainties in Solar Wind Forecasting Due to Incomplete Solar Magnetic Field Information
Stephan G. Heinemann, Jens Pomoell, Ronald M. Caplan +5
Solar wind forecasting plays a crucial role in space weather prediction, yet significant uncertainties persist due to incomplete magnetic field observations of the Sun. Isolating t…
