Question

Quizplus · Accepted Answer

Red giant stars are much larger and brighter than main sequence stars, and therefore appear above and to the right of them on the Hertzsprung-Russell diagram. Blue giant stars, while also larger and brighter than main sequence stars, appear below and to the left of them on the diagram. White dwarf stars are much smaller and cooler than main sequence stars, and appear below and to the right of them on the diagram. Subgiants are intermediate in size and brightness between main sequence and giant stars, and fall between them on the diagram.
