Large bright stars that are fairly cool are called?
Red giants.
Which stars are very cool but very luminous?
Red supergiant stars, such as Betelgeuse and Antares, are examples of stars that are very cool in temperature while still being extremely luminous due to their large size and high brightness. Despite their cool surface temperatures, they radiate a tremendous amount of energy into space.
The large cool stars found at the upper right of the H-R diagram are stars?
The large, cool stars found at the upper right of the H-R diagram are red giants. These stars are in a later stage of their evolution, where they have exhausted their core hydrogen fuel and expanded in size. They are cooler in temperature but have a large luminosity due to their increased surface area.
What color are small cool stars?
Small cool stars, such as red dwarfs, are typically red or orange in color. This is because their surface temperatures are relatively low, causing them to emit more red and orange light compared to other colors.
What is the classification of about 90 percent of the stars?
About 90 percent of stars are classified as main sequence stars, which means they are in the stable phase of their lifecycle where they are fusing hydrogen into helium in their cores. These stars follow a pattern on the Hertzsprung-Russell diagram known as the main sequence.
Large bright stars that are fairly cool are called?
Red giants.
What stars are cool and bright stars?
To be bright you need to be hot, close or have a large surface area. The brightest coolest stars are red super giants. They have such a large surface area, that even though their surface temperature is cool - in star terms - their large surface area makes them appear bright.
What characteristics do red stars share?
They are either small and cool and fusing hydrogen or large and hot, fusing helium. The large and hot ones ape read because although they are hot, this heat is radiated over a large surface area. Large red stars are approaching the end of their lives, small, cool red stars will have very, very long lives.
Stellar-classification?
Madalynne Braseltonstellar classification is the classification of stars based on their spectral characteristics
What is the red giant galaxies and classification?
The red giant galaxies are large non-main sequence star of stellar classification. These are classified K or M because of the reddish appearance of the cooler giant stars.
Which stars are very cool but very luminous?
Red supergiant stars, such as Betelgeuse and Antares, are examples of stars that are very cool in temperature while still being extremely luminous due to their large size and high brightness. Despite their cool surface temperatures, they radiate a tremendous amount of energy into space.

Are dwarf stars relatively hot or cool?
cool
What is the classification of the brown bear?

What is classification for small hot stars?
white dwarfs
