Abstract-

White dwarfs and neutron stars are the most common endpoints of stellar evolution and provide extreme environments for fluid dynamics. I will summarize recent work on the non-radial oscillations of white dwarfs, especially those accreting material from a nearby orbiting star. The recent discovery of coherent oscillations from these objects allows for new probes of the interior structure and rotation rate within the star. Oscillations in neutron stars have not yet been firmly detected, but the physics is so rich that I will provide an overview of their properties and describe the likely difficulties with detection by X-ray satellites.
