Resumen:
We will discuss the possibility that the observed multiperiodic photometric variability in He-rich sdOBV stars is caused by stochastically excited g-modes driven by unstable He burning. We will show that such mechanism is able to excite pulsations with periods and amplitudes similar to those observed in LS IV-14º 116 and Feige 46.
