Magnetic field variations and the seismicity of solar active regions

TL;DR

This paper investigates how magnetic field variations in solar active regions may generate seismic waves, or sunquakes, by analyzing magnetic data during specific solar flares and comparing with other observations.

Contribution

It provides a detailed analysis of magnetic field forces as a mechanism for sunquake generation, supporting the hypothesis proposed by previous researchers.

Findings

Magnetic field variations correlate with sunquake activity.

Spatial and temporal magnetic analysis supports magnetic forces as a plausible mechanism.

Comparison with other observations reinforces the magnetic origin hypothesis.

Abstract

Dynamical changes in the solar corona have proven to be very important in inducing seismic waves into the photosphere. Different mechanisms for their generation have been proposed. In this work, we explore the magnetic field forces as plausible mechanisms to generate sunquakes as proposed by Hudson, Fisher and Welsch. We present a spatial and temporal analysis of the line-of-sight magnetic field variations induced by the seismically active 2003 October 29 and 2005 January 15 solar flares and compare these results with other supporting observations.
