Exploring if a coronal dimming event can produce coronal hole-like properties

Adriana De-Sassi, Louise Harra, Krzysztof Barczynski +8

Coronal dimmings, or transient coronal holes, are manifested as a sudden reduction in extreme ultraviolet (EUV) and X-ray emission, often following solar eruptions. We investigate…

Current Helicity in Response to Coronal Mass Ejections

Zheng Sun, Ting Li, Xinkai Bian +3

Coronal mass ejections (CMEs), powerful solar eruptions with massive plasma ejected into the interplanetary space, are caused by the release of the magnetic free enengy stored in c…

The temporal evolution of non-neutralized electric currents and the complexity of solar active regions

I. Kontogiannis, M. K. Georgoulis

We study the evolution of electric currents during the emergence of magnetic flux in the solar photosphere and the differences exhibited between solar active regions of different H…

Spectral Background-Subtracted Activity Maps

Carsten Denker, Meetu Verma, Alexander G. M. Pietrow +2

High-resolution solar spectroscopy provides a wealth of information from photospheric and chromospheric spectral lines. However, the volume of data easily exceeds hundreds of milli…

The characteristics of flare- and CME-productive solar active regions

Ioannis Kontogiannis

Solar flares and coronal mass ejections (CMEs) cause immediate and adverse effects on the interplanetary space and geospace. The deeper understanding of the mechanisms that produce…

Multiple Stokes I inversions to infer magnetic fields in the spectral range around Cr I 5782 Å

C. Kuckein, H. Balthasar, C. Quintero Noda +8

The spectral window, containing Fraunhofer lines formed in the solar photosphere, around the magnetically sensitive Cr I lines at 5780.9, 5781.1, 5781.7, 5783.0, and 5783.8 Å, with…
