Luminosity
(L) : is the rate of light energy released or power output of a star.
·
Intensity (1) : is the luminosity per unit crea from star a
I :

Luminosity
I d = distance from source (star)
·
Intensity follows the inverse square low meaning it is
inversely proportional
to the square of the distance between the star and observer .

A standard candle is an object of known
luminosity Ce g .

Cepheid variable stars
You can measure astronomical distances by the intensity detected
