THE EFFECT OF INSTABILITY OF SOLAR PROMINENCE

Abstract

Solar prominence research critically relies on the Cartesian coordinate system, providing a framework for mapping prominence features, tracking their evolution, analyzing their motion, and comparing observations with theoretical models. This study utilized a three-dimensional Cartesian system to investigate prominence dynamics, specifically tracking the motion of plasma knots. A key finding was the observation of a significant acceleration phase immediately prior to eruption, strongly supporting the hypothesis of magnetic reconnection as the primary driver of this phenomenon. This observed pre-eruption acceleration, coupled with the analysis of plasma knot trajectories within the 3D Cartesian framework, allowed for a more precise determination of the reconnection site and the energy release rate. These findings have significant implications for improving space weather forecasting models, particularly those related to predicting coronal mass ejections and their potential impact on Earth's magnetosphere.
