Abstract: We present accurate radial velocity measurements on the pulsating extremely iron-deficient post-AGE object HD 52961 and the RV Tauri star EN TrA (HD 131356) proving them to be binaries. Our long-term photometric monitoring campaign shows that the RV Tauri photometric class "b" phenomenon in HD 52961 is due to variable circumstellar extinction during orbital motion.
