Abstract: We report on our continuing search for planets around pulsating white dwarf stars. All stars with a main sequence mass less than ∼1 MSolar are expected to become white dwarf stars (WDs), so a search for planets around WDs is a search around the evolutionary end point of a wide range of main sequence spectral types. The range of spectral types also means a broad range of main-sequence lifetimes enabling us to probe planet formation rates as a function both of spectral type and Galactic history. We present data for three stars in our sample and predict the region of mass-orbital separation space explored by monitoring these stars for just three years.
