Sun core temperature, Sun Radiative Layer, Convection Zone

 

What are the layers of the sun made up of? Hydrogen is the basic element of all the stars of the universe, not only the Sun. (Sun core temperature) Elements like Helium, Carbon, Oxygen, Neon are further formed by the process of fusion. But our sun does not have that much mass to fuse elements to make heavy elements. 

The Sun is a small star that is made up of up to 70% hydrogen and helium. If the sun is considered to be a hollow sphere, then it is mainly filled with hydrogen and helium plasma in this form.

With different layer decorations. And only this material fuses and gives us more energy. Which we enjoy today. The main source of energy on earth is the energy of the sun. 

 

Sun Core Temperature 

The core of the Sun consists of only 20 to 25% of the Sun in size. The core of the Sun, that is, the temperature of the center part, is as hot as 15 million degrees Celsius. (27 million degrees Fahrenheit) The core of the very dense Sun is the main engine of the Sun. Hydrogen atoms in the center of the Sun fuse to form helium and generate energy through nuclear fusion. 

The density of the sun core is 150 grams per centimeter. There are too many. This is more than 150 times the density of water. 99% of the energy that comes out of the sun comes from the sun core itself. (Convection Zone) The Sun releases energy at a mass-energy conversion rate of 426 million metric tons per second, which is as much as 384.6 watts. 

 

Sun Radiative Layer 

Above the core is the radiative zone, out of the layers of the sun, it is a thick layer of 3.5 lakh kilometers. This layer is slightly less dense than the core. Regarding this layer, the amount of light produced inside the core of the Sun takes up to 1 lakh 70 thousand years to cross the radiative zone and reach the next layer. 

Although it is less dense than the core, this does not mean that we can imagine its density. 

Therefore, it takes up to 1 lakh 70 thousand years for the light to pass from the core to the radiative zone. Talking about the temperature, it heats up to about 7 million degrees Celsius. This radiative zone is .7 times the radius of the Sun. And the density of this layer of the Sun has to change from a centimeter cube at 20 grams to a centimeter at 0.2 grams. 

 

Convection Zone 

The layer of convection zone is above the radiative zone, its plasma is not very dense. As much as the core and radiative zone. This layer is less thick than the rest of the sun’s layers. And it is the outermost layer of the layers of the sun. Its thickness is about 20 lakh kilometers. 

The photosphere represents the bright surface of the Sun and has a temperature of about 5600°C. Here solar radiation is visible in the form of light. Sunspots on the photosphere are darker and cooler regions than the surrounding regions. In the center of large sunspots, temperatures can drop to 4000°C.

Due to such a large difference between the temperatures, a convection process takes place on this layer, which radiates the heat outwards. 

The density of the material present in this layer is 0.2 g/m3. If we telescope towards the sun and try to see this layer, then we will see. There are some dark spots above the sun. And the shape and size of these dark spots also change continuously.

The reason for the formation of these dark spots is that bundles of magnetic fields come out in the form of energy from the convection zone inside. Through a telescope, scientists can also see inside these dark spots.
