Refinements to the Solar Polar Magnetic Flux: Implications from Inversion Methodologies

Bryan Yamashiro, Xudong Sun, Ivan Milić +6

The magnetic fields in the solar polar region are important to our understanding of the internal dynamo process, the global coronal structure, and the origin of the solar wind. The…

What Can DKIST/DL-NIRSP Tell Us About Quiet-Sun Magnetism?

Jiayi Liu, Xudong Sun, Peter W. Schuck +1

Quiet-Sun regions cover most of the Sun's surface; its magnetic fields contribute significantly to the solar chromospheric and coronal heating. However, characterizing the magnetic…

Emerging Dimming as Coronal Heating Episodes

Anna V. Payne, Xudong Sun

Emerging dimming occurs in isolated solar active regions (ARs) during the early stages of magnetic flux emergence. Observed by the Atmospheric Imaging Assembly, it features a rapid…
