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…
Identification of Coronal Holes on AIA/SDO images using unsupervised Machine Learning
Fadil Inceoglu, Yuri Y. Shprits, Stephan G. Heinemann +1
Through its magnetic activity, the Sun governs the conditions in Earth's vicinity, creating space weather events, which have drastic effects on our space- and ground-based technolo…
How to Estimate the Far-Side Open Flux using STEREO Coronal Holes
Stephan G. Heinemann, Manuela Temmer, Stefan J. Hofmeister +3
Global magnetic field models use as input synoptic data, which usually show "aging effects" as the longitudinal 360° information is not obtained simultaneously. Especially during t…
Multi-channel coronal hole detection with convolutional neural networks
R. Jarolim, A. M. Veronig, S. Hofmeister +4
We develop a reliable, fully automatic method for the detection of coronal holes, that provides consistent full-disk segmentation maps over the full solar cycle and can perform in…
Coronal Hole Detection and Open Magnetic Flux
J. A. Linker, S. G. Heinemann, M. Temmer +14
Many scientists use coronal hole (CH) detections to infer open magnetic flux. Detection techniques differ in the areas that they assign as open, and may obtain different values for…
Statistical Approach on Differential EmissionMeasure of Coronal Holes using the CATCH Catalog
Stephan G. Heinemann, Jonas Saqri, Astrid M. Veronig +2
Coronal holes are large-scale structures in the solar atmosphere that feature a reduced temperature and density in comparison to the surrounding quiet Sun and are usually associate…
