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):.
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
The difference between luminosity and apparent brightness depends on distance
. ... Thus, the equation for the apparent brightness of a light source is given by ...
Dec 26, 2012 ... Luminosity of a Star. ... Introductory Astronomy: Luminosity, Temperature, and
Surface Area - Duration: 16:15. P.E. Robinson 5,084 views. 16:15 ...
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).
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.
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
Magnitude - Distance Formula - used to give the relationship between the
apparent ... Luminosity-Radius-Temperature - the formula that relates these three
Mar 11, 2016 ... We use the equation below to solve for the star's luminosity, relative to the sun's,
where L = luminosity and T = surface temperature, and the ...
