  Irregular moons are a class of satellite found orbiting all of the Solar
System's giant planets: as their orbits don't match those of their planets,
they are theorised to have formed elsewhere in the Solar System and were
subsequently captured into their observed orbits. Missions such as Cassini have
contributed significant empirical data on irregular moons in the present day
but this paper aims to develop our currently limited theoretical understanding
of their origins and capture as it presents one of the first projects to
connect moon capture with another feature common to all giant planets: ring
systems. As a captured body gravitationally brakes around a ringed planet, it
transfers orbital energy to the planetary system, a process which has been seen
to leave distinctive signatures on the rings which may be used to constrain key
parameters of this interaction, including the trajectory and timing. This paper
presents a project which applies this technique to constrain scenarios for moon
capture through conducting a series of computational simulations using the
Python version of the astrophysical code REBOUND modelling the capture of the
large irregular moon Phoebe by the planet Saturn and Phoebe's effect on
Saturn's ring system. By helping to constrain scenarios for moon capture, this
research will further our understanding of the moon systems of the giant
planets while simulating the effects of a moon's interaction with a ring system
will offer insight into the formation and evolution of planetary rings, whether
within our own Solar System or orbiting exoplanets.
