Luminosity and Temperature of Stars
An article about Astronomy & Deep Space
Refer to the HR Diagram (Hertzsprung-Russell Diagram) (Characteristics of Stars chart) page 15 of the Earth Science Reference Tables
This chart is also known as the HR Diagram. The HR Diagram is a plot of luminosity versus surface temperature of the stars.
The points on the diagram represent stars. Most of the stars (about 90%) fall on the main sequence (this is not a place in space but is a relationship between temperature and luminosity). As temperature increases, energy emitted increases, resulting in an increase in brightness.
Most of the stars that are not located are Supergiants, Red Giants, or White Dwarfs.
