Basic Properties of the Stars
... If two stars have the same temperature, each square meter gives off the same amount of light (E = σ T4). If one of the two stars has 100 times the luminosity of the other, it must have 100 times the surface area, or 10 times the diameter. Hertzsprung and Russell realized that the stars at the ...

Astronomical spectroscopy
Astronomical spectroscopy is the study of astronomy using the techniques of spectroscopy to measure the spectrum of electromagnetic radiation, including visible light, which radiates from stars and other hot celestial objects. Spectroscopy can be used to derive many properties of distant stars and galaxies, such as their chemical composition, temperature, density, mass, distance, luminosity, and relative motion using Doppler shift measurements.
