  We present a small collection of FUSE spectra representative of the main
spectral classes found in white dwarf stars. In addition, we also discuss
another family of hot evolved stars, that of the hot subdwarfs. Both families
belong to the chemically peculiar stars, and it is thought that a complex
interplay of competing processes such as gravitational settling, ordinary
diffusion, radiative levitation, weak stellar winds, and accretion is
responsible for the rich variety of atmospheric compositions observed in those
objects. FUSE is playing a key role in the current quest for establishing a
coherent theory of the spectral evolution of these stars as it allows the
determination of the patterns of heavy element abundances at a significantly
higher level of accuracy than has been possible before on the basis of optical
or UV observations. We also briefly present some fascinating FUV light curves
of a handful of pulsating subdwarf B stars, thus illustrating the unique
potential of FUSE for asteroseismological studies, a potential which has not
been exploited yet.
