| Abstract: |
It was shown in Gusakov & Kantor (2011) that equations governing
oscillations of superfluid neutron stars
can be split into two systems of weakly coupled equations,
one describing the superfluid modes
and another one,
the normal modes.
Here we demonstrate that
similar decoupling of modes also occurs in rotating NSs.
To this aim we formulated
the relativistic hydrodynamics of superfluid mixtures
allowing for vortices.
Our results indicate,
in particular,
that emission of gravitational waves
from superfluid oscillation modes
is suppressed in comparison to that from normal modes.
The proposed approach allows one to drastically simplify
modeling of oscillations of superfluid rotating neutron stars. |
