Abstract
Eclipsing binary stars with pulsating components are especially valuable for studies of stellar evolution. We have discovered that three eclipsing binary stars in the southern sky have a pulsating component with oscillations similar to those of δ Scuti stars. The systems are: AW Velorum, HM Puppis and TT Horologii. Their spectral types were determined as A7 for AW Vel and HM Pup and F0-F2 for TT Hor. The dominant pulsation frequencies are 15 – 38 cycles per day with amplitudes of 10 – 60 millimagnitudes.
