A sequence of high-luminosity degenerate stellar models with hydrogen shell burning near the surface has been constructed. The models have carbon-oxygen cores and hydrogen envelopes. The luminosities lie in the range from 0.1 to 10,000 times the solar luminosity. The masses are 1.0 and 0.6 solar mass. Values for periods, eigenfunctions, and stability integrals are presented. The models in the luminosity range from the solar value to 1000 times that value are unstable in the fundamental mode. At 10 times the solar luminosity, the first harmonic is unstable. The models may be relevant to pulsating X-ray sources and white dwarfs.
