Cool prominences in the corona of the rapidly rotating dMe star, HK Aquarii.


Abstract (from CDS):

We report the discovery of cool, prominence-like material embedded in the hot corona of the rapidly rotating dMe flare/spot variable, HKAqr. Using these observations we demonstrate that, unlike the case of the rapidly rotating K dwarf, ABDor, these features form well below the co-rotation radius. Rather they have dimensions between 3-20 times those of the very largest solar prominences. At least seven clouds were detected during each stellar rotation and they have a lifetime of greater than the three nights spanned by our data.
