How is this equation derived? It is simply an application of the luminosity ratio
Mar 23, 2015 ... If you know how much energy the star emits (its luminosity), then you can ... In
formula form, this means the star's flux = star's luminosity / (4 pi ...
What is the equation/Formula for finding the luminosity of a star in ... This Site
Might Help You. RE: What is the Formula for Determining the ...
The difference between luminosity and apparent brightness depends on distance
. ... Thus, the equation for the apparent brightness of a light source is given by ...
The brightness of a star of a given luminosity L, radiated in all directions, falls ...
The basic formula relating the apparent (m) and absolute (M} magnitudes then is.
General formula for luminosity is given as: L = 4 π r 2 b. Above formula is used
when we know the distance and brightness ...
The luminosity of a star is given by the equation. L = 4pR<sup>2</sup>s T<sup>4</sup>,. Where L is the
luminosity in Watts, R is the radius in meters, s is the Stefan-Boltzmann constant
