The nonradially pulsating GW Vir (a.k.a. DOV, or pulsating PG1159) stars and the K1–16 type variable stars provide an unparalleled opportunity to probe the internal structure of planetary nebula central stars and their immediate descendants, hot pre-white dwarfs. Recent global photometry campaigns have provided data of sufficient quality to severely constrain evolutionary models of these stars.
