How deep is the convection zone

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, Web29 de out. de 2024 · Determine the value of the constant W in the deep convection zone, using γ = 1.67 and μ = 0.61. As expected, here the agreement with the accurate model is …

WebIn the convection zone Ω = Ω (θ), largely independent of radius r, and in the radiative zone Ω is approximately constant. At the interface of the two zones is a thin layer, of no more than 5% of Solar radius, in which the angular velocity has large radial gradients. This is known as the tachocline [ 195, 196 ]. Fig. 6.
