Helioseismology can be used to place new constraints on the properties of dark matter, allowing solar observations to complement more conventional dark matter searches currently in operation. During the course of its lifetime, the Sun accretes a sizeable amount of dark matter. This accreted matter affects the heat transport of the stellar core in ways that helioseismology can detect, or at least constrain. We modify the CESAM stellar evolution code to take account of dark matter and determine the effect of WIMP models on the stellar structure and normal-mode oscillation frequencies.
