When the Sun exhausts its hydrogen fuel in the core and finishes the main sequence stage, it will enter the red giant phase. During this stage, the core will contract and heat up, causing the outer layers to expand significantly. Eventually, the Sun will shed its outer layers, creating a planetary nebula, while the core will remain as a white dwarf.
This happens when a main sequence star uses up all of its fuel and swells. Next stage: Red Giant.
The sun is currently in the main sequence stage. Next, it will evolve into a red giant as it depletes its hydrogen fuel and starts burning helium in its core.
The Main Sequence stage.
The star will move on to its next stage of evolution, along the Red Giant branch.
Our sun is a main sequence (dwarf) star. It's expected to remain so for the next 5 billion years or so. After that it will expand briefly into a red giant, then collapse into a white dwarf.

white dwarf. unless you count black dwarf of which none have been observed, only theorized.

it is fusion of hydrogen into helium. (like our sun) if it is a red giant (the next stage of our suns life) it is burning helium into denser things.
The word "next" tells the reader that this is not the main idea, because it is next in the sequence of the paragraph. There is a sentence before it that would be the main idea.
It will become a red giant.
A protostar transitions to the next stage in the stellar cycle, known as a main sequence star, when it achieves sufficient temperature and pressure in its core to initiate nuclear fusion of hydrogen into helium. As the core contracts and heats up, the outward pressure from fusion balances the inward gravitational force, leading to a stable state. This marks the end of the protostar phase and the beginning of the star's main sequence phase, where it will spend the majority of its life. The transition is often accompanied by the clearing of surrounding material, revealing the newly formed star.
After a stellar nebula, the next stage in stellar evolution depends on the mass of the star that forms from it. For a low to medium mass star, like our Sun, the nebula condenses to form a protostar, which eventually evolves into a main sequence star. In contrast, for more massive stars, after the protostar stage, they also enter the main sequence phase but will eventually progress to more complex stages, leading to supernova events and the formation of neutron stars or black holes.
The next letter in the sequence AAAAA is 'E'. It is a vowel sequence.
