Theoretical instability strip for rapid p-mode pulsations in hot subdwarfs. The small black dots identify grid points corresponding to stable models. Each red point identifies a model where unstable modes are predicted, the size of the dot being proportional to the number of excited modes. The blue circles show the location of sdBVr variables among the field population, while the black cross indicates the one known rapid sdO variable in the field. The five sdO variables we found in ω Cen are represented by black circles, the dotted extension to higher log g for V2 indicating that the polluted spectrum obtained yields only a lower limit on the surface gravity.
