A radiation zone, or radiative region is a layer of a star's interior where energy is primarily transported toward the exterior by means of radiative diffusion and thermal conduction, rather than by convection. Energy travels through the radiation zone in the form of electromagnetic radiation as … See more In a radiative zone, the temperature gradient—the change in temperature (T) as a function of radius (r)—is given by: where κ(r) is the opacity, ρ(r) is the matter density, L(r) is the … See more Eddington assumed the pressure P in a star is a combination of an ideal gas pressure and radiation pressure, and that there is a constant ratio, β, of the gas pressure to the total pressure. Therefore, by the ideal gas law: See more For main sequence stars—those stars that are generating energy through the thermonuclear fusion of hydrogen at the core, the presence … See more • SOHO ...
