Abstract
Some 27 h of high-speed photometric monitoring of the sdB + star PB 8783 has revealed it to be a rapidly pulsating star of the EC 14026 class. Six periodicities in the range 120 to 135 s have been tentatively identified in the light curve. The pulsation amplitudes of all the modes are small, mostly below 5 mmag. Spectrograms show the star to be composite, and UBVRIJHK photometry indicates that the companion to the subdwarf is of early-F spectral type.Keywords
