Supergiants are even more luminous than giants. Supergiants can have any temperature, but they are always VERY luminous, with L = 100,000 to 1,000,000 L sun. Supergiants are VERY rare, but are VERY easy to detect, because of their VERY high luminosity. White Dwarfs are less luminous than a main sequence star of the same temperature. They are

abundance analysis of very cool stars was also noticed by Smith & Lambert (1990), who found that the strong OH 1-0 and 2-0 bands gave unreasonably large oxygen abundances compared with those based on the weaker bands and that strong CO lines cannot be used for abundance analysis as well. The carbon and oxygen abundances in other stars are by no

Cool class M stars, having temperatures of only about 3000 K and being much less luminous than our sun, surprisingly show very active chromospheres and coronas—in some cases, with higher far-UV fluxes per unit area than our sun. These cool stars also sometimes exhibit flare activity far surpassing that of our sun.

Astronomers Grapple with JWST’s Discovery of Early Galaxies | Scientific American These superluminous stars, which are at the upper left of the H-R diagram, are exceedingly hot, very blue stars of spectral type O. These are the stars that would be the most conspicuous at vast distances in space. The cool supergiants in the upper corner of the H-R diagram are as much as 10,000 times as luminous as the Sun. In addition
