Radiative & Convective Zones - THE SOLAR SYSTEM

NettetAround the core lie two layers: a thick layer called the radiative zone and a thinner, cooler layer called the convective zone. Surrounding all of them is the sun’s surface layer, known as the photosphere. Above this lies the sun’s thin atmosphere, which is made up of the chromosphere and the corona. Nettet25. apr. 2024 · The radiative zone is a thick layer of highly ionized, very dense gases which are under constant bombardment by the gamma rays from the core. It is about 75% hydrogen and 24% helium. Because most of the atoms here lack electrons, they … Main sequence stars below about 0.3 solar masses are entirely convective, meaning they do not have a radiative zone. From 0.3 to 1.2 solar masses, the region around the stellar core is a radiation zone, separated from the overlying convection zone by the tachocline. Se mer A radiation zone, or radiative region is a layer of a star's interior where energy is primarily transported toward the exterior by means of radiative diffusion and thermal conduction, rather than by convection. Energy travels … Se mer In a radiative zone, the temperature gradient—the change in temperature (T) as a function of radius (r)—is given by: where κ(r) is the opacity, ρ(r) is the matter density, L(r) is the luminosity, and σB is the Se mer For main sequence stars—those stars that are generating energy through the thermonuclear fusion of hydrogen at the core, the presence … Se mer • SOHO ...

NettetCore starts from center till 0.2 Solar radius almost 139,000 km thick. The second part of sun’s interior is the Radiative Zone starts at the edge of the core of the Sun and extends up to about 0.7 solar radius almost 350,000 Km thick. Energy from the core bounces in this region & take 170,000years to get from core to convective zone. NettetThe Radiation Zone. The radiation zone is just outside the core. The function of this layer is to transfer energy from the core to the other layers. The temperature at this layer is cooler than the core at 7 million degrees Fahrenheit causing thermal radiation. This layer has 60 percent mass and 90 percent volume. The Convection Zone

NettetIn 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.

NettetAbout 250 miles thick and averaging about 10,000 degrees Fahrenheit, this layer emits the white light we can see with our eyes.

NettetThis zone has a thickness of 300000 Km. The energy is radiated through the plasma. That energy is released as photons "Υ" and that radiation is absorbed and re-emitted thousand times before leaving the upper layers converted into Y, X & ultraviolet rays, visible light and infra-red (heat). Nettet16. jun. 2024 · The radiative zone is the second inner layer of the Sun. It sits outside of the core, and it holds its extremely high temperature. The zone itself has a temperature of around 7 million degrees Fahrenheit. This layer serves as a passage for all the energy that is released by the core.
