| **Numerical Modeling:** The star is divided into **concentric shells (zones)**, and differential equations are replaced by **difference equations**. Solutions require matching **boundary conditions** at the center ($M_r \to 0, L_r \to 0$) and surface ($P \to 0, T \to 0$).\\ | **Numerical Modeling:** The star is divided into **concentric shells (zones)**, and differential equations are replaced by **difference equations**.
