Scientific paper

I present the results of time-resolved photometry of a selection of central
stars of planetary nebulae. The study reveals periodic variability in two of
the eight central stars observed, those of NGC 6026 and NGC 6337. The
variability matches that expected from a binary system in which a hot primary
irradiates a cooler secondary star.
