Small cool star of low luminosity
WebbA red giant is a luminous giant star of low or intermediate mass (roughly 0.3–8 solar masses ( M☉ )) in a late phase of stellar evolution. The outer atmosphere is inflated and tenuous, making the radius large and the surface temperature around 5,000 K (4,700 °C; 8,500 °F) or lower. Webblow luminosity. Stellar evolution: A star forms when a dense interstellar cloud of hydrogen and dust grains collapses inward under the force of its own gravity. As the cloud condenses, its density and internal temperature increase until reaching incandescence with a faint red glow. At this stage the star

WebbThe low masses of the stars cause the nuclear fusion reactions at their cores to proceed exceedingly slowly, giving them luminosities ranging from a maximum of roughly 10 percent that of the Sun to a minimum of just 0.0125 percent. [12]
WebbAt the top end of the main sequence, the stars are large, hot, and very luminous. Because of their size and color, they are referred to as blue giants. The very largest are called blue supergiants. At the other end, stars are small, cool, and faint. They are known as red dwarfs. Our Sun lies right in the middle.
