Researchers introduce new 'filament channel' function to predict solar eruptions triggered by emerging flux

A study published in The Astrophysical Journal Letters, introduces a newly defined "filament channel" function. This new function provides a novel theoretical foundation for predicting solar eruptions by determining whether new emerging flux (NEF) can trigger instability in solar filaments. The study was led by Prof. Lin Jun from the Yunnan Observatories of the Chinese Academy of Sciences.
