Main Sequence Structure
Numerical solutions to the equations of stellar structure can provide detailed description of the interiors of stars. Some general features of stellar structure can be discovered through these solutions. The mass distribution indicates that for high-mass stars with M ≥ 1. 2 M⊙ over 95 % of the mass is contained within ∼ 60 % of the radius. For lower-mass stars, this extends out to about 80 % of the radius. Naturally, the energy production is significantly higher in high-mass stars and extends out to larger radii.
