@article { , title = {A statistical correlation of sunquakes based on their seismic and white-light emission}, abstract = {Several mechanisms have been proposed to explain the transient seismic emission, i.e. “sunquakes,” from some solar flares. Some theories associate high-energy electrons and/or white-light emission with sunquakes. High-energy charged particles and their subsequent heating of the photosphere and/or chromosphere could induce acoustic waves in the solar interior. We carried out a correlative study of solar flares with emission in hard X-rays, enhanced continuum emission at 6173 Å, and transient seismic emission. We selected those flares observed by the Reuven Ramaty High Energy Solar Spectroscopic Imager (RHESSI) with a considerable flux above 50 keV between 1 January 2010 and 26 June 2014. We then used data from the Helioseismic and Magnetic Imager onboard the Solar Dynamic Observatory to search for excess visible-continuum emission and new sunquakes not previously reported. We found a total of 18 sunquakes out of 75 flares investigated. All of the sunquakes were associated with an enhancement of the visible continuum during the flare. Finally, we calculated a coefficient of correlation for a set of dichotomic variables related to these observations. We found a strong correlation between two of the standard helioseismic detection techniques, and between sunquakes and visible-continuum enhancements. We discuss the phenomenological connectivity between these physical quantities and the observational difficulties of detecting seismic signals and excess continuum radiation.}, doi = {10.1007/s11207-015-0786-9}, eissn = {1573-093X}, issn = {0038-0938}, issue = {11}, journal = {Solar physics}, pages = {3151-3162}, publicationstatus = {Published}, publisher = {Springer Verlag}, url = {https://hull-repository.worktribe.com/output/441283}, volume = {290}, keyword = {Lasers and Light Matter Interactions, Specialist Research - Other, Helioseismology, Flares, white light flares}, year = {2015}, author = {Buitrago-Casas, J.
