Since the 1970s it has been empirically known that the area of solar coronal holes a ects the properties of high-speed solar windstreams (HSSs) at Earth. We derive a simple analytical model for the propagation of HSSs from the Sun to Earth and thereb

Context. Interplanetary collisionless shocks are known to be sources of energetic charged particles up to hundreds of MeV. However, the underlying acceleration mechanisms are still under debate.Aims. We determine the properties of suprathermal proton

Publikováno v: Astronomy & Astrophysics. 636:A103

Context. 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 affected by both. This means that reliably determining the so

Evolution of an equatorial coronal hole structure and the released coronal hole wind stream: Carrington rotations 2039 to 2050

Autor: Thies Peleikis, Robert F. Wimmer-Schweingruber, Lars Berger, Verena Heidrich-Meisner, Martin Kruse

The Sun is a highly dynamic environment that exhibits dynamic behavior on many different timescales. In particular, coronal holes exhibit temporal and spatial variability. Signatures of these coronal dynamics are inherited by the coronal hole wind st
