Stars become Red Giants when the main sequence ends in a star which can be different periods of time depend on if it is a high-massive star or a low-massive star. :)
Blue giants.
They are red giants.
Red giants. By the way, what if it was a white star.
Red Giants and black holes
the red giant phase is about the end of a stars life. it will last for about one million years.
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.

No. Only massive stars can become supergiants.
Not exactly. Red giants become white dwarf stars. It is the red supergiants that can become supernovas.
Yes red giants are the largest. But the bigger stars of red giants can be called red hyper giants.
No. Intermediate mass stars will evolve into Red Giants and then to White Dwarfs. See related questions for more information.
Stars expand in size to become red giants, when they start running low on Hydrogen fuel.
No, they are mostly red dwarf stars.
No. Red giants are when stars become even bigger than they were before. Our sun will become a red giant in a few billion years. When it does, it will destroy earth.
when Dwarf Stars run out of hydrogen they form Red Giant stars, then from that they become White dwarf stars when the outer layers shed, forming a planetary nebula.when giant stars or supergiant stars run out of hydrogen they form red supergiant stars
The large hot stars are typically called "blue-white" stars or also Blue Giants. Cooler large stars are called Red Giants.
