Seismic Holography of the Solar Interior and Far Side
Published online by Cambridge University Press: 13 May 2016
Extract
The development of solar acoustic holography over the past decade has opened a major new diagnostic avenue in local helioseismology (Lindsey & Braun 1990; 1997; 2000b). Its application to SOI-MDI data from SOHO has revealed “acoustic moats” surrounding sunspots, “acoustic glories” surrounding complex activeregions, and “acoustic condensations” suggesting the existence of significant seismic anomalies up to 20 Mm beneath active-region photospheres. It has given us the first seismic images of a solar flare, and has uncovered a remarkable anomaly in the statistical distribution of seismic emission from acoustic glories. A review of these and other accomplishments is given by Braun & Lindsey (2000a).
