WebChapter 12 Hertzsprung Russel Diagram Plots the luminosities and temperatures of stars Stellar Luminosity Luminosity: Amount of power a star radiates (energy per second = watts) Apparent brightness: Amount of starlight that reaches Earth (energy per second per square meter) Luminosity of a star is an intrinsic property based on temperature and size, also … WebThe main features of the Hertzsprung-Russell diagram are: Most stars lie on the Main Sequence. This is the band of stars going from top left to bottom right. Below the main sequence (and slightly to the left) are the White Dwarfs. Above the main sequence on the right-hand side are the Red Giants. Above those are the Red Supergiants.
