Comparison of Helioseismic Far-side Active Region Detections with STEREO Far-Side EUV Observations of Solar Activity
P. C. Liewer, J. Qiu, C. Lindsey
Seismic maps of the Sun's far hemisphere, computed from Doppler data from the Helioseismic and Magnetic Imager (HMI) on board the Solar Dynamics Observatory (SDO) are now being use…
Are all flare ribbons simply connected to the corona?
Philip Judge, Alin Paraschiv, Daniela Lacatus +2
We consider the observational basis for the belief that flare ribbons in the chromosphere result from energy transport from the overlying corona. We study ribbons of small flares u…
Helioseismic Holography of Simulated Sunspots: dependence of the travel time on magnetic field strength and Wilson depression
T. Felipe, D. C. Braun, A. C. Birch
Improving methods for determining the subsurface structure of sunspots from their seismic signature requires a better understanding of the interaction of waves with magnetic field…
Sensitivity of Helioseismic Measurements of Normal-mode Coupling to Flows and Sound-speed Perturbations
Shravan M. Hanasoge, Martin Woodard, H. M. Antia +2
In this article, we derive and compute the sensitivity of measurements of coupling between normal modes of oscillation in the Sun to underlying flows. The theory is based on first-…
Vortex and sink flows in eruptive flares as a model for coronal implosions
Francesco P. Zuccarello, Guillaume Aulanier, Jaroslav Dudík +3
Eruptive flares are sudden releases of magnetic energy that involve many phenomena, several of which can be explained by the standard 2D flare model and its realizations in three-d…
Evaluating (and Improving) Estimates of the Solar Radial Magnetic Field Component from Line-of-Sight Magnetograms
K. D. Leka, G. Barnes, E. L. Wagner
Although for many solar physics problems the desirable or meaningful boundary is the radial component of the magnetic field , the most readily available measurement is t…
