WebConvection Zone: This area forms the outer shell of the Sun. Energy is transferred very quickly in this zone through convection. Hotter gas from the radiative zone expands and rises through the convection zone. It can do this because the convective zone is cooler than the radiative zone, and therefore less dense. Web30 de mar. de 2024 · In each numerical run, convection cells are first initiated with dense concentration C = 1 everywhere. At each time step, Equations ( 1 ) and ( 2 ) are numerically advanced, and then and are calculated, using Poisson equation solvers for the curl of Equations ( 3 ) and ( 4 ).

Web10 de out. de 2012 · It reaches from the surface visible at the center of the solar disk to about 250 miles (400 km) above that. The temperature in the photosphere varies between about 6500 K at the bottom and 4000 K at the top (11,000 and 6700 degrees F, 6200 and 3700 degrees C). Most of the photosphere is covered by granulation. WebAlthough there are no fires on the surface of the Sun, the photosphere seethes and roils, displaying the effects of the underlying convection. Photons flowing from below, trapped by the underlying layers, finally escape. This produces a dramatic drop in temperature and density.
