Abstract

We demonstrate a possibility of existence of a peculiar temperature-dependent composition gg-modes in superfluid neutron stars. We calculate the Brunt-Va¨\ddot{\rm a}isa¨\ddot{\rm a}la¨\ddot{\rm a} frequency for these modes, as well as their eigenfrequencies. The latter turn out to be rather large, up to 500\sim 500 Hz for a chosen model of a neutron star. This result indicates, in particular, that use of the barotropic equation of state may be not a good approximation for calculation of inertial modes even in most rapidly rotating superfluid neutron stars.
