Definition of giant star in English English dictionary: A star that has stopped fusing hydrogen in its core and as a result has grown much larger and brighter; large star of higher than average luminosity; A large, bright star The brightness of a star depends on its size and temperature A giant star is brighter than a dwarf star of the same temperature; Any of a class of highly luminous, exceptionally massive stars. Star with a relatively large radius for its mass and temperature; this yields a large radiating area, so such stars are bright. Subclasses include supergiant stars, red giants (with low temperatures, but very bright), and subgiants (with slightly reduced radii and brightness). Some giants are hundreds of thousands of times brighter than the Sun. Giants and supergiants may have masses 10-30 times that of the Sun and volumes millions of times greater and are thus low-density stars; a very bright star of large diameter and low density (relative to the Sun); A star of greater luminosity and larger size than a main sequence star of the same temperature; Large, cool, highly luminous star in the upper right of the H-R diagramm Typically 10-100 times the diameter of the Sun
