From Gigahertz to Millihertz: A Multiwavelength Study of the Acoustically Active 14 August 2004 M7.4 Solar Flare

Abstract: We carried out an electromagnetic acoustic analysis of the solar flare of 14 August 2004 in active region AR10656 from the radio to the hard X-ray spectrum. The flare was a GOES soft X-ray class M7.4 and produced a detectable sun quake, confirming earlier inferences that relatively low energy flares may be able to generate sun quakes. We introduce the hypothesis that the seismicity of the active region is closely related to the heights of coronal magnetic loops that conduct high-energy particles from the flare… Show more

“…The evidence provided by Martínez-Oliveros et al (2007, 2008b suggests that low lying coronal loops are more likely to be conducive to a more rapid injection of trapped electrons into the chromosphere at their footpoints. This enhances the magnitude and suddenness of the chromospheric heating that gives rise to the intense visible continuum emission seen in all flares with detectable seismic activity.…”

“…They also argued in favour of the need for a source agent that acted relatively suddenly, a qualification further emphasized by Martínez-Oliveros et al (2007, 2008a, who discovered significant seismic emission in relatively small flares.…”

“…We have touched on several areas of application. Although we have not discussed it here, there have also been a number of recent papers resulting from the holographic study of the seismic response of the solar interior to flares, which should improve our understanding of flare physics (Donea, 2006;Kosovichev, 2007;Martinez-Oliveros et al, 2007;Moradi et al, 2007;Zharkova and Zharkov, 2007).…”
