A window into delta Sct stellar interiors using eclipsing binary systems.

Our knowledge of the structure of the sun, solar-like stars, and red giants has advanced significantly using asteroseismology. However, the relationship between observed asteroseismic pulsations and the fundamental parameters of delta-Sct stars remains largely elusive. We can utilise binary systems with delta-Sct components to determine the precise parameters of the pulsating star. With well-characterised delta-Sct stars, together with identified pulsation modes, more reliable modelling of pulsation modes is possible. From this basis, models of single delta-Sct can be validated.
