Web30 de jul. de 2024 · Near the bottom of the convection zone, T0(Rc.z. ) ≈ 2.3 × 106 K. Near the surface, T0(R ⊙) / T0(Rc.z. ) ≈ 10 − 3, which vanishes to a good approximation. The convection-zone radius Rc.z. = R ⊙ − Hc.z. , where Hc.z. ≈ 200 Mm is the convection-zone depth, and R ⊙ ≈ 696 Mm is the solar radius ( Table 1 ). Therefore,
