Research news on flare

In the context of physical phenomena, a flare is a transient, intense increase in electromagnetic radiation and often particle emission from an astrophysical object, typically associated with rapid energy release in a magnetized plasma. Solar and stellar flares arise from magnetic reconnection in the corona, converting stored magnetic energy into heating, particle acceleration, and broadband radiation from radio to gamma rays on timescales of seconds to hours. Flares are characterized by impulsive and gradual phases, nonthermal electron and ion populations, and can drive associated phenomena such as coronal mass ejections, shock waves, and disturbances in surrounding magnetized environments.
