Overview
Core model: Stellar Interiors & Energy Transport
A star's interior is organized by the competition among gravity, nuclear energy generation, opacity, and energy transport. Energy produced in hot central regions reaches the surface mainly through radiation or convection, and the dominant transport process can change with depth and stellar mass.
