How the area of solar coronal holes affects the properties of high-speed solar wind streams near Earth -- An analytical model
Stefan Johann Hofmeister, Eleanna Asvestari, Jingnan Guo +10
We derive a simple analytical model for the propagation of HSSs from the Sun to Earth and thereby show how the area of coronal holes and the size of their boundary regions affect t…
An elliptic expansion of the potential field source surface model
Martin Kruse, Verena Heidrich-Meisner, R. F. Wimmer-Schweingruber +1
Context. The potential field source surface model is frequently used as a basis for further scientific investigations where a comprehensive coronal magnetic field is of importance.…
Proton-proton collisional age to order solar wind types
Verena Heidrich-Meisner, Lars Berger, Robert F. Wimmer-Schweingruber
The properties of a solar wind stream are determined by its source region and by transport effects. Independently of the solar wind type, the solar wind measured in situ is always…
Disparity among low first ionization potential elements
Verena Heidrich-Meisner, Lars Berger, Robert F. Wimmer-Schweingruber
The elemental composition of the solar wind differs from the solar photospheric composition. Elements with low first ionization potential (FIP) appear enhanced compared to O in the…
Observations of high and low Fe charge states in individual solar wind streams with coronal-hole origin
Verena Heidrich-Meisner, Thies Peleikis, Martin Kruse +2
The solar wind originating from coronal holes is comparatively well-understood and is characterized by lower densities and average charge states compared to the so-called slow sola…
Evolution of an equatorial coronal hole structure and the released coronal hole wind stream: Carrington rotations 2039 to 2050
Verena Heidrich-Meisner, Thies Peleikis, Martin Kruse +2
The Sun is a highly dynamic environment that exhibits dynamic behavior on many different timescales. In particular, coronal holes exhibit temporal and spatial variability. Signatur…
