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.
It will expand and become a red giant.
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.
The next stage in the sun's life cycle will be the red giant phase. During this phase, the sun will expand and become bigger, eventually engulfing the inner planets of our solar system.
The next stage in the life cycle of the Sun is the red giant phase. During this phase, the Sun will expand and cool, becoming larger in size and engulfing planets, including Earth. This phase is followed by the shedding of its outer layers to form a planetary nebula, leaving behind its core as a white dwarf.
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.
A blue giant star goes through multiple stages during its life cycle: formation from a collapsing nebula, main sequence where it fuses hydrogen into helium, red giant phase where it expands and fuses heavier elements, and finally, depending on its mass, it may end as a supernova or a black hole.
It will expand and become a red giant.

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.
The sun's red giant stage will last for 1 or 2 billion years.
The biggest star - VY Canis Majoris IS in a red supergiant phase and will explode as a massive supernova.
After its main sequence phase, a star like the Sun will enter the red giant phase where it expands and becomes cooler. Subsequently, it may evolve into a planetary nebula and eventually form a white dwarf.
No. The Sun is a main-sequence star. It will not be a red giant for another 5 billion years.(see related link for an image of what the Sun would look like in its red giant phase
A star that is in it's teenage years(medium star) isn't a red giant until it's last years.
