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…

Velocity and Density Fluctuations in the Quiet Sun Corona
Michael Hahn, Xiangrong Fu, Stefan J. Hofmeister +3
We investigate the properties and relationship between Doppler-velocity fluctuations and intensity fluctuations in the off-limb quiet Sun corona. These are expected to reflect the…

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…
