Radiative Zone

The radiative zone is a region in the interior of a star where energy is primarily transported by radiation. It is located between the stellar core and the convective zone.

Key Concepts

• Radiation Transport: In the radiative zone, energy is carried by photons (electromagnetic radiation) as the primary mode of heat transfer.
• Temperature and Density: The radiative zone is characterized by high temperature and density, which allows for efficient radiation transport.
• Nuclear Fusion: The energy released from nuclear fusion reactions in the core of the star is gradually transported through the radiative zone via radiation.
