Abstract: We demonstrate how pulsating white dwarfs can be used as an astrophysical laboratory for empirically constraining convection in these stars. We do this using a technique for fitting observed non-sinusoidal light curves, which allows us to recover the thermal response timescale of the convection zone (its “depth”) as well as how this timescale changes as a function of effective temperature. We also obtain mode identifications for the pulsation modes, allowing us to use asteroseismology to study the interior structure of these stars.
