Abstract: It is shown by a fully non-adiabatic analysis that nuclear reactions in the hydrogen burning-shell excite low-degree g-modes in the period range of about 40-200 s for the hydrogen-dominated atmosphere pre-white dwarf models with Teff= 40 000 K - 300 000 K. The amount of hydrogen has a significant influence on the instability domain of such pre-white dwarfs in the Hertzsprung-Russel (H-R) diagram. Hence, the thickness of hydrogen-dominated envelopes may be well constrained by observing the presence of the g-mode oscillations.
