What type of stars have high absolute magnitude but low temperatures?
Red giants.
Are red giant stars the largest?
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.
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.
Do blue stars and red giant stars have similar brightness values?
Blue stars are generally much brighter than red giant stars. Blue stars are very hot and luminous, emitting a larger amount of energy compared to red giants, which are cooler and typically less bright.

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 type f stars are in the milky way galaxy?
The Milky Way galaxy contains a variety of stars, including main sequence stars (like our Sun), giants, supergiants, white dwarfs, and neutron stars. The most common stars are red dwarfs, making up about 70-80% of all stars in the Milky Way. There are also many other types of stars, such as yellow dwarfs (like our Sun), blue giants, and red giants.

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.
