This lecture introduces solar physics, covering the convective and radiative zones of the Sun, its nuclear energy source, magnetic field structure, and the proton-proton chain reaction. It explores the properties of the Sun, such as its distance, mass, radius, luminosity, and elemental abundances. The lecture delves into the luminosity-mass dependence for main sequence stars, hydrostatic equilibrium, and the temperature profile in the Sun's interior. It discusses energy transport mechanisms, opacity in plasmas, and the escape of photons. The lecture also touches on convection, sunspots, the solar cycle, and the global magnetic field structure of the Sun.
