Hot Spine Loops and the Nature of a Late-Phase Solar Flare
Xudong Sun, J. Todd Hoeksema, Yang Liu +4
The fan-spine magnetic topology is believed to be responsible for many curious features in solar explosive events. A spine field line links distinct flux domains, but direct observ…

On the Coordinate System of Space-Weather HMI Active Region Patches (SHARPs): A Technical Note
Xudong Sun
We describe the coordinate systems of two streams of HMI active region vector data. A distinction is made between (a) the 2D grid on which the field vector is measured (or sampled)…

Reflection and refraction of (magneto-)acoustic waves at the magnetic canopy: further evidences from multi-height seismic data
S. P. Rajaguru, Xudong Sun, K. Hayashi +1
We recently presented evidences (Rajaguru et al. 2012) that seismic halos around expanding magnetic structures in the lower solar atmosphere are related to the acoustic to magnetoa…
