Abstract
A radial oscillation model of accretion discs for quasi-periodic light variations in cataclysmic variables is examined by means of numerical simulations. It is known that when the α model is used for the viscosity, accretion discs around compact objects are overstable against radial axisymmetric oscillations under a variety of conditions. The calculations demonstrate that radial oscillations of the accretion discs around white dwarfs yield quasi-periodic oscillations (QPOs) in the disc of luminosity L d . The calculated QPO periods are ∼80-400 s for α = 0.1 and for the mass-transfer rate of ∼10 17 -10 19 g/s
