  The photometric variations due to magnetically confined material around
He-strong stars are investigated within the framework of the Rigidly Rotating
Magnetosphere (RRM) model. For dipole field topologies, the model is used to
explore how the morphology of light curves evolves in response to changes to
the observer inclination, magnetic obliquity, rotation rate and optical depth.
  The general result is that double-minimum light curves arise when the
obliquity and/or inclination are close to 90 degrees; no light variations are
seen in the opposite limit; and for intermediate cases, single-minimum light
curves occur. These findings are interpreted with the aid of a simple,
analytical torus model, paving the way for the development of new
photometric-based constraints on the fundamental parameters of He-strong stars.
Illustrative applications to five stars in the class are presented.
