This star could fit into the category of red giants.
Red giants are stars that have expanded and cooled after exhausting the hydrogen fuel in their cores. As a result, they have a low surface temperature but can possess a high luminosity due to their large size. This contrasts with other categories like red dwarfs, which are low in both luminosity and temperature, and white dwarfs, which are hot but not very luminous despite their high temperatures.
