Class M stars are to cool for that much x-ray emission from surface. ii.b. Comes from Stellar Coronas with a temp. of 1,000,000k magnetic waves. iii. Ultraviolet observations iii.a. Can pick up spectral line from a temp. of 250,000. iii.b. Come from Stellar Chromospheres/Transition zone between surface and corona. H-R Diagrams a graphical representation of the relationship or absolute magnitude, temperature, color and spectral type of stars. There are four major sections on an H-R Diagrams: Supergiants, Giants, Dwarfs (main Sequence) and White Dwarfs. Mass-Luminosity Relationship .
