What is a structure of the star?

Question

Like the earth has a structure has a inner core, outer core, mantle, and crust. And how it is made.

Answer 1

The Sun (or any other star) has structure.

There is a Core where the majority of the heat is generated via fusion of hydrogen into helium.

There is a Radiation Zone where the intense heat of the core is transmitted outward.

There is a Convection Zone where the heated plasma from below is circulated to the photosphere where it cools and falls back to be reheated.

Then there's the Photosphere... the visible surface of the Sun.

Next is the Atmosphere... which is comprised of five principal zones: the temperature minimum, the chromosphere, the transition region, the corona, and the heliosphere. The heliosphere, which may be considered the tenuous outer atmosphere of the Sun, extends outward past the orbit of Pluto to the heliopause, where it forms a sharp shock front boundary with the interstellar medium. The chromosphere, transition region, and corona are much hotter than the surface of the Sun; the reason why is not yet known.

Answer 2

Yes, stars have structure too. At the center is the core. This is where the fusion occurs due to temperature and pressure. Depending on the size and age of the star, the core may be in layers where the inner most layer is fusing a heavier element such as carbon and an outer layer is fusing helium and a still outer layer is fusing hydrogen. This is referred to as "shell burning".
Outside the core structure is a radiative zone where energy is radiated outward from the core. The size of this zone depends on the size of the star and its mass.
The next zone outward is the convection zone. It is cooler and is very similar in function and structure as the earth's mantle (except it is mostly hydrogen instead of magma). There may be more than one layer of the convection zone.
The surface of the star is the photosphere. This is where the hot gasses radiate light and heat out into space. As the gasses cool, they sink back down into the convection layer again.
Finally there is the corona. The corona is the closest thing a star has to an atmosphere. The corona is generally very large, but due to the disbursement of atoms, it contains very little heat.

Answer 3

The sun is mainly hydrogen.
The core is a fusion furnace and also contains helium.
In larger stars heavy elements collect in layers,until iron occurs then the star collapses and explodes in a super nova.
