Nuclear Fusion in Astrophysics inside Stars
Nuclear fusion in astrophysics inside stars describes the mechanism by which stellar interiors maintain hydrostatic equilibrium through thermonuclear reactions converting light nuclei into heavier elements, thereby releasing binding energy via mass defect conversion ($E=mc^2$). This process is governed by quantum tunneling probabilities under conditions of extreme thermal pressure and density within gravitational confinement. It represents the primary internal energy generation mechanism for main-sequence stars in galactic populations, distinct from terrestrial fusion reactors or fission-based processes.
