How deep is the convection zone
WebIn the Sun's photosphere, the most ubiquitous phenomena are granules — convection cells of plasma each approximately 1,000 km (620 mi) in diameter with hot rising plasma in the center and cooler plasma falling in the spaces between them, flowing at velocities of 7 km/s (4.3 mi/s). Webzone, they provide information about the depth of the convection zone, but not about the structure of the regions deeper down. To investigate these deeper parts of the sun one …
How deep is the convection zone
Did you know?
WebFirst, the timescale of deep convection in the ocean is sufficiently long that it may be modified by the Earth’s rotation; second, the convective process is localized in space so that vertical buoyancy transfer by upright, non-hydrostatic convection can give way to slantwise transfer by baroclinic instability in balanced, geostrophic motion ... 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.

In red giant stars, and particularly during the asymptotic giant branch phase, the surface convection zone varies in depth during the phases of shell burning. This causes dredge-up events, short-lived very deep convection zones that transport fusion products to the surface of the star.
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 ).
