This quantity is equal to four pi R squared times sigma times temperature to the fourth power by a law derived from the Stefan-Boltzmann equation.
The Schechter function gives the number of stars or galaxies with a given value for this property. Some stars that emit especially powerful stellar wind are in excess of four pi times big G times big M times proton mass times speed of light over sigma, the Eddington limit for this quantity. This quantity is equal to four pi R squared times sigma times temperature to the fourth power by a law derived from the Stefan-Boltzmann equation. The type of this quantity that considers all light wavelengths is called bolometric. For 10 points, give this astronomical quantity measured by a star's absolute magnitude.
