Contribution

It introduces a novel triangulation tracking method to observe radially propagating MHD waves in solar active regions after flares.

Findings

Detection of radially propagating MHD waves in active regions

Correlation between flare energy release and acoustic oscillation excitation

Enhanced understanding of wave behaviors in chaotic solar environments

Abstract

For decades it has been established that the amount of energy released by solar flares excites the acoustic oscillations propagating on the surface of the Sun (Wolff 1972). It is believed that these flares can excite velocity oscillations in active regions, especially those regions where a higher class solar flare has taken place (Kumar 2006). However, questions arise as to how the behaviors of acoustic oscillations within such a chaotic environment can birth other waves of the MHD type. Can we observe such events?
