Why does the amount of hydrogen in a star decrease over time?
The amount of hydrogen in a star decreases over time because the star fuses hydrogen into helium in its core through the process of nuclear fusion. This conversion of hydrogen into helium releases energy that powers the star and results in a gradual depletion of its hydrogen fuel source.
What inevitably forces a star like the Sun to evolve away from being a main sequence star?
The main factor that causes a star like the Sun to evolve away from being a main sequence star is the depletion of hydrogen fuel in its core. As the hydrogen fuel is used up, the core contracts and heats up, leading to the outward expansion of the star's outer layers. This expansion and change in structure lead the star to evolve into a red giant.
When the sun ages after awhile what does it contain?
As the sun ages, it undergoes processes that lead to the depletion of its hydrogen fuel in the core. This results in the expansion of the outer layers, turning the sun into a red giant. Eventually, it will shed its outer layers to form a planetary nebula, leaving behind a dense core called a white dwarf composed mostly of carbon and oxygen.
Where does hydrogen fusion occur when there is no hydrogen left in the core of a star?
If there is no hydrogen left at the core of star then hydrogen fusion cannot occur. What happens in the core of a star before that happens is that helium begins to fuse, and then the other elements going up the periodic table until carbon. And then if the star explodes into a supernova, traces of the higher elements are fused as well.
What type of stars are red giants?
These are stars that have exhausted their core's supply of hydrogen by switching to a thermonuclear fusion made of hydrogen in a shell that surrounds the core.
Why is the depletion of hydrogen in the core of a star such an important event?
The depletion of hydrogen in the core of a star is important because it triggers the next stage of the star's life cycle, leading to the fusion of helium and the release of energy. This process sustains the star's brightness and heat, allowing it to continue shining and supporting life on surrounding planets.

Does the sun and the earth have a hydrogen core?
There's hydrogen at the core of the sun - that's the sun's main fuel - but earth's core is mostly iron and nickel.
How many core electrons In hydrogen?
Hydrogen has one core electron. Core electrons are those in the inner energy levels of an atom and are not involved in chemical bonding.

What is in the suns core?
helium and hydrogen
Why does a star's hydrogen supply run out?
A star's hydrogen supply runs out because of nuclear fusion in its core. As hydrogen is fused into heavier elements like helium, the star's core temperature increases, causing it to expand and cool. Eventually, the core runs out of hydrogen to fuse, leading to the star's evolution into a different phase.
Does Jupiter have a dense core of hydrogen and helium?
No, it has a dense rocky core in the middle!!
How does the sun create energy it is core?
Nuclear Fusion from hydrogen in it core and helium
Saturn planet air core?
Saturn is a gas giant composed mainly of hydrogen and helium, with no solid surface. It is believed to have a small rocky core at the center, surrounded by metallic hydrogen and a layer of molecular hydrogen.
