Abstract

We combine a grid of high-resolution theoretical intensity spectra with simulated non-radially pulsating stellar surfaces for a variety of pulsation modes. These are used to simulate the light curves in a number of photometric pass bands. We attempt to provide diagnostics for identifying the modes in pulsating sdB stars KPD 2109+4401 and HS 0039+4302.
