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.

Are red giant stars the largest?
Yes red giants are the largest. But the bigger stars of red giants can be called red hyper giants.
What type of stars have high absolute magnitude but low temperatures?
Red giants.
What color are small cool stars?
The large hot stars are typically called "blue-white" stars or also Blue Giants. Cooler large stars are called Red Giants.
Are main sequence stars older than red giants?
No, red giants are generally older than main sequence stars, as red giants have no hydrogen left for fuel, and burn helium instead. where as Main Sequence stars burn hydrogen for fuel.
What is the classification for large cool stars?
red giants
What type of star is Star A?
Red stars (Red dwarfs and red giants) have a spectral class of M.

Is the nearest stars mostly red giants?
No, they are mostly red dwarf stars.
What color are small cool stars?
The large hot stars are typically called "blue-white" stars or also Blue Giants. Cooler large stars are called Red Giants.
What are Featureless galaxies containing old red main-sequence stars and red giants called?
If they have red stars including giants in, they can't be all that featureless.
Why do stars not become red giants?
Most medium mass stars such as our Sun DO become red giants. Smaller stars do not have enough mass to initiate helium fusion when the hydrogen supply begins to run low, and do not become red giants.
What do all stars eventually turn into?
All stars eventually turn into Red Giants or Super Giants
What are red stars called?
I think you are referring to red giants.
Are main sequence stars older than red giants?
No, red giants are generally older than main sequence stars, as red giants have no hydrogen left for fuel, and burn helium instead. where as Main Sequence stars burn hydrogen for fuel.
Are there different types of red giants?
Yes, there are. The classic red giants that come from sun- like stars, and red supergiants come from blue giants.
