which stars have low temperatures and high luminosities?\nred giants\nwhite dwarfs\nmain sequence stars
Answer
Brief Explanations:
By observing the graph, red - giants are in the region of low temperatures (lower right side of the temperature axis) and high luminosities (upper part of the luminosity axis). White dwarfs have low luminosities and main - sequence stars do not have both low temperatures and high luminosities simultaneously.
Answer:
red giants
