Solar plasma physics is a research field within plasma physics and astrophysics dedicated to studying the physical properties, dynamics, and electromagnetic interactions of the highly ionized matter (plasma) that comprises the Sun. This area investigates fundamental processes such as energy generation and transport, magnetohydrodynamic phenomena driving solar activity (including flares, coronal mass ejections, and the solar wind), and the solar dynamo, providing essential insights into stellar structure, evolution, and space weather.
