During the red giant phase, a star has typically exhausted the hydrogen in its core, leading to hydrogen fusion occurring in a shell surrounding the inert helium core. The outer layers of the star may still contain some hydrogen, but the core hinders further hydrogen fusion. The amount of hydrogen present varies depending on the star's mass and its evolutionary history, but it is significantly less than during the main sequence phase.

What fuses during the red giant phase?
During the red giant phase, hydrogen fusion occurs in the shell surrounding the helium core. The core is no longer fusing hydrogen, as it has already converted most of its hydrogen into helium. This causes the outer layers of the star to expand and cool, leading to the red giant phase.
Which type of fusion occurs in the red giant phase?
The primary type of fusion that occurs in the red giant phase is helium fusion. As the star's core runs out of hydrogen fuel, it contracts and heats up to the point where helium fusion can begin, converting helium into carbon and oxygen. This process generates energy and causes the star to expand and become a red giant.
Stage where the star swells?
The stage where a star swells into a red giant is called the red giant phase, typically occurring when a star runs out of hydrogen fuel in its core and starts to fuse helium in its shell. During this phase, the star expands and cools, turning redder in color due to its lower surface temperature.
What is the next stage in the suns evolution?
The next stage in the Sun's evolution is the red giant phase. This occurs when the Sun runs out of hydrogen fuel in its core and starts burning helium. During this phase, the Sun will expand and become larger, eventually engulfing Mercury, Venus, and possibly Earth.
What happens to the sun when it runs out of hydrogen?
It becomes a red giant, expanding until it is larger than earth's orbit. Meanwhile it begins helium fusion (3 heliums --> 1 carbon). Eventually, all possible conversion scenarios are used up, and that is the end of the line. The interior of the star collapses onto itself forming a very dense "white dwarf", and the red giant exterior is forcibly blown off as an expanding bubble.

Is the big red giant Jupiter?
No, Jupiter is not a red giant. Jupiter is a gas giant planet in our solar system, primarily composed of hydrogen and helium, while red giants are much larger dying stars that have exhausted their hydrogen fuel and expanded.
When does the dying phase of a massive star begin?
The dying phase of a massive star begins when it runs out of usable hydrogen that it can convert to helium. Once it becomes a red giant, it slowly dies out.
What is the next stage in the suns evolution?
The next stage in the Sun's evolution is the red giant phase. This occurs when the Sun runs out of hydrogen fuel in its core and starts burning helium. During this phase, the Sun will expand and become larger, eventually engulfing Mercury, Venus, and possibly Earth.

Where does the energy for the fusion in the red giant come from?
A red giant is a star that has (to a great extent, at least) run out of hydrogen; it will therefore fuse hydrogen into heavier elements.
Will the sun explode?
No, the sun will not explode. It is currently in the main sequence phase of its life cycle, converting hydrogen to helium through nuclear fusion. Eventually, it will expand into a red giant and then shrink into a white dwarf.
What causes a giant?
After a star burns up all it's hydrogen, it becomes a red giant.
The star begins to run out of fuel and expands Into a red giant or red super giant?
No. That is when stars run out of hydrogen. They then have helium for fuel.
When does a star enter its third stage?
A star enters its third stage, known as the red giant phase, when it exhausts the hydrogen fuel in its core and starts fusing helium into heavier elements. During this phase, the star expands and becomes much larger in size.
