They lie in the star cluster R136 … A star whose initial mass is less than approximately 0.25 M☉ will not become a giant star at all. For most of their lifetimes, such stars have their interior thoroughly mixed by convection and so they can continue fusing hydrogen for a time in excess of 1012 years, much longer than the current age of the Universe. Ver más 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 Ver más There are a wide range of giant-class stars and several subdivisions are commonly used to identify smaller groups of stars. Subgiants Ver más 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.
