Our study focuses on eclipsing binary system. The variations in light
intensity from eclipsing binary stars are caused when a star passes in front of
the other relative to an observer. If we assume that the stars are spherical and
that they have circular orbits, then we can easily calculate how the light
varies as a function of time, which is called a light curve, for eclipsing
binary stars. The discovery and detection of eclipsing binary systems comes
from measuring the variation of the intensity of light through photometry.
The observed light intensity varies as the stars move through their orbits.
The light curves clearly show the effects of movement of the components of
the system.
