Jfrom the study of variable stars. Most stars are constant in their luminosity, at least to within a percent or two. Like the Sun, they generate a steady flow of energy from their interiors. However, some stars are seen to vary in

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). ALL of the star's light passes through the surface area of this sphere but only a small fraction passes through the instrument aperture. The fraction of the star's rate of light energy emission measured by the instrument is…
