| Abstract: | We examine the possible emission of gravitational waves from white dwarfs undergoing self-similar oscillations driven by the
energy released during relaxation of their differential rotation. Two distributions of the initial angular momentum are considered.
It is assumed that 1% of the energy dissipated by a rotating white dwarf is converted into the energy of self-similar oscillations
and, therefore, into gravitational radiation. The relative amplitude of the gravitational radiation from an isolated white
dwarf at a distance of 50 pc is found to be less than 10−27. The emission from the galactic population of white dwarfs may create a background which overlaps the random cosmological
background of gravitational radiation for the improved decihertz detectors currently being proposed.
