ISIS is a program that specializes in detecting variable stars within clusters, both open and
globular. ISIS has historically been used in surveys searching for variable stars. However,
recent work has identified new uses for ISIS, such as the detection of exoplanet transits in
clusters of stars. This thesis will evaluate ISIS, both how the program functions and for which
objects it is most efficient and appropriate. I examined five clusters: three open, and two
globular, for one night surveys. With this survey, I identified twenty-five variable stars.
Twenty-two variables were previously known, and three variable stars were previously
undiscovered. In total, from my short one night surveys, I confirmed twenty-five previously
known variable stars and four unknown variable stars. Furthermore, ISIS has detected several δ
Scuti stars whose amplitude of variation is on par with an exoplanet transit. These data suggest
that ISIS can be used for the detection of exoplanet transits. / Department of Physics and Astronomy
