The Stefan–Boltzmann equation applied to a black body gives the value for
luminosity for a black body, an idealized object ...
Science - Formulas. ... Physics - Formulas - Luminosity ... if we know distance and
brightness of a star, we can determine its Luminosity (or actual brightness):.
This equation allows you to find the energy of a moving object if its mass and
velocity are ... VARIABLES: L, is Luminosity of the emitter, (in Joules per second).
Luminosity Formula. The student is given the radius/temperature/luminosity of a
star as compared to the sun and is asked to determine what 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 luminosity of a star depends upon radius and surface temperature. ... In the
equation below L = luminosity and R = radius. Let's say the radius of the star is 5
Dec 26, 2012 ... Luminosity of a Star. ... Introductory Astronomy: Luminosity, Temperature, and
Surface Area - Duration: 16:15. P.E. Robinson 5,824 views. 16:15.
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.
How is this equation derived? It is simply an application of the luminosity ratio
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
