A Coronal Cavity Gets a Chewy Nougat
|
This movie combines Hinode XRT with Hinode SOT Ca II H-line data to demonstrate how a coronal cavity gets a chewy nougat. A chewy nougat is solar slang for hot X-ray emission in the center of a coronal cavity, usually sitting just above a cool prominence. So why does a cool solar prominence have such a hot head? In this case, hot X-ray plasma slams into the prominence, causing cool prominence material to flow along an arc. Eventually, hot X-ray emission develops near the prominence tip.

magnetometry research topic.
