Recent work published by Lindsey et al. find evidence for a deep and compact seismic source for the sunquake associated with the 2011 July 30 M9.3 flare, as well as seismic emission extending up to 10 mHz. We examine the sunquake independently, and a possible wave front is found in the 8 mHz band, though no wave front is easily discernible in the 10 mHz band. Additionally, we perform numerical simulations of seismic excitation modeled with the reported parameters and changes in the power… 



Submerged Sources of Transient Acoustic Emission from Solar Flares

We report the discovery of ultra-impulsive acoustic emission from a solar flare, emission with a seismic signature that indicates submersion of its source approximately a Mm beneath the photosphere

Estimation of Key Sunquake Parameters through Hydrodynamic Modeling and Cross-correlation Analysis

Sunquakes are one of the more distinct secondary phenomena related to solar flares, where energy deposition in the lower layers of the Sun’s atmosphere excites acoustic waves easily visible in

Helioseismic Holography

We describe the basic principles of “helioseismic holography,” an analytic technique intended for local helioseismology of subsurface structure. The purpose of this technique is to provide depth

The Current State of Solar Modeling

Data from the GONG project and other helioseismic experiments reveal subtle errors in the models, such as an excess in sound speed just beneath the convection zone, which is plausible that the sound-speed differences reflect weak mixing in stellar interiors.

X-ray flare sparks quake inside Sun

Solar flares involve a release of the Sun's magnetic energy as X-radiation, particle beams and high-speed plasma flows. But we have discovered, using data from the Solar and Heliospheric Observatory
