What kind of star becomes a giant when fusion slows down the outer atmosphere of the star expands luminosity increases and the star begins to fuse helium into carbon?

A star that becomes a giant under these conditions is typically a red giant. This transformation occurs when a star exhausts hydrogen in its core, leading to a slowdown in fusion, expansion of its outer layers, and an increase in luminosity. As the core contracts and heats up, helium fusion begins, allowing the star to produce heavier elements like carbon. This phase is common in stars that start with a mass similar to or greater than that of the Sun.
