Brightness and Luminosity 31 The brightness or flux intensity of a star at an observer's location may be determined by measuring the rate at which its light enters the aperture of an observing instrument (this is referred to as photometry). We will call this "" (with units [Energy/time/Area] or [Watts/Area]). Imagine a sphere of radius, d (labeled "p" in the figure below), equal to the star's distance from the observer's location, at which the star is at the center (see the figure below).
