For the first time nonradial oscillations of superfluid nonrotating stars are
self-consistently studied at finite stellar temperatures. We apply a realistic
equation of state and realistic density dependent model of critical temperature
of neutron and proton superfluidity. In particular, we discuss three-layer
configurations of a star with no neutron superfluidity at the centre and in the
outer region of the core but with superfluid intermediate region. We show, that
oscillation spectra contain a set of modes whose frequencies can be very
sensitive to temperature variations. Fast temporal evolution of the pulsation
spectrum in the course of neutron star cooling is also analysed.
