CHAPTER 10, Stellar Motions
... Astronomers have now detected hundreds of planetary bodies, called exoplanets, moving in orbit around other stars. Most of these are more massive than any of the Sun's planets. These planetary-like bodies are detected because of their strong gravitational interactions with their stars. However, tech ...

... Just as brightness is related to apparent magnitude, luminosity is related to a term called “absolute magnitude.” Astronomers refer to a star’s “absolute magnitude (M)” as the apparent magnitude it would have at an arbitrary standardized distance of 10 parsecs (i.e., 32.6 light-years). #2.

Luminosity and brightness
... Luminosity is a measure of the total energy given output by a star at all wavelengths form gamma radiation to radio waves. For example the Sun gives out about 500 million million million MJ of energy every second so its luminosity is 500 million million million MJ. The luminosity depends on: (a) the ...
