X-ray Variability and the Secondary Star
Abstract
We discuss the history of X-ray observations of the η Car system, concentrating on the periodic variability discovered in the 1990s. We discuss the interpretation of these variations, concentrating on a model of the system as a "colliding-wind" binary. This interpretation allows the physical and orbital parameters of η Car and its companion star to be constrained.
