How do giant stars form
WebMay 4, 2024 · The more massive a star is, the hotter its core temperature reaches, and the faster it burns through its nuclear fuel. As a star's core runs out of hydrogen to fuse, it contracts and heats up,... A giant star is a star with substantially larger radius and luminosity than a main-sequence (or dwarf) star of the same surface temperature. They lie above the main sequence (luminosity class V in the Yerkes spectral classification) on the Hertzsprung–Russell diagram and correspond to luminosity … See more A star becomes a giant after all the hydrogen available for fusion at its core has been depleted and, as a result, leaves the main sequence. The behaviour of a post-main-sequence star depends largely on its mass. See more There are a wide range of giant-class stars and several subdivisions are commonly used to identify smaller groups of stars. Subgiants Subgiants are an entirely separate spectroscopic luminosity class (IV) from giants, but share … See more • Interactive giant-star comparison. See more

Although giant stars are a different kind of star from average main-sequence stars, it isn’t actually formed right away. Instead, stars go through the main-sequence phase for a long time, perhaps billions of years, before entering the giant phase, which lasts much shorter than the main-sequence phase.
