Super red giant stars
WebA red giant is a giant star in the late stage of its stellar evolution that has exhausted its supply of hydrogen. Red giant stars have a yellow-orange to red appearance. A star with a solar mass between 0.3 and 8.0 will evolve into red giant. The average surface temperature of a red giant is between 4,000 and 5,800 degrees Fahrenheit. WebRed Giants and Supergiants Two stars at the same spectral type, say type G, can have quite different brightnesses. One could be a main sequence star with M = +5 and the other a giant star with M = –2.5.
