it is called the photoflare
A star might begin to die after its main sequence. It'll balloon to a very big size. They're called red giants because the star is big and red. A red giant can die, though. Red giants die when their surface sheds into a cloud called a planetary nebula. Its core becomes a white dwarf. Our sun will go through this path.
Red giants. By the way, what if it was a white star.
They are red giants.
Stars become red giants when they have exhausted their hydrogen fuel in the core and start burning helium, causing the outer layers to expand and cool. This expansion turns the star into a large, cool, and luminous red giant.
It is called the core, also known as the inner core. It is located under the outer core. The outer core sits under the mantle (the big red part).

I think you are referring to 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.
If they have red stars including giants in, they can't be all that featureless.

They are red giants.
It is called the Mundle. Sense it between the crust and the core it is red.
With red giants and main sequence stars they are not entirely featureless, therefore there is no name for them.
They're called gas giants because of this fact.
No, red giant stars are not the largest stars in the universe. There are stars known as supergiant and hypergiant stars that are even larger than red giants. These stars can be hundreds to thousands of times larger than our Sun.
The stars that are like supergiants are called "red giants" or "red supergiants".
