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…
Modeling the evolution and propagation of the 2017 September 9th and 10th CMEs and SEPs arriving at Mars constrained by remote-sensing and in-situ measurement
Jingnan Guo, Mateja Dumbović, Robert F. Wimmer-Schweingruber +13
On 2017-09-10, solar energetic particles (SEPs) originating from the active region 12673 were registered as a ground level enhancement (GLE) at Earth and the biggest GLE on the sur…
