A Point-Spread Function for the Extreme Ultraviolet High-Resolution Imager on board Solar Orbiter
Stefan J. Hofmeister, Emil Kraaikamp, Sergei Shestov +7
We present the point-spread function (PSF) of the Extreme Ultraviolet High-Resolution Imager (HRIEUV) onboard Solar Orbiter, which observes the Sun at 174 Angstrom. This PSF provid…

Formation of a Coronal Hole by a quiet-Sun Filament Eruption
Stefan J. Hofmeister, Eleanna Asvestari, Karin Dissauer +9
A coronal hole formed as a result of a quiet-Sun filament eruption close to the solar disk center on 2014 June 25. We studied this formation using images from the Atmospheric Imagi…

Elemental Abundances at Coronal Hole Boundaries as a Means to Investigate Interchange Reconnection and the Solar Wind
Alexandros Koukras, Daniel W. Savin, Michael Hahn
The origin of the slow solar wind is not well understood, unlike the fast solar wind which originates from coronal holes. In-situ elemental abundances of the slow solar wind sugges…
