The first numerical study of axial (toroidal) pulsation modes of a slowly rotating relativistic star is presented. The calculation includes terms of first order in ϵ ≡ Ω(R3/M)1/2 ≪ 1 (R is the radius, M is the mass, and Ω is the rotation frequency of the star) and accounts for effects due to the Coriolis force. Effects due to the centrifugal flattening of the star enter at order ϵ2 and are not included in the analysis. It is shown that increased rotation tends to decrease the damping times for…

The r-Mode Oscillations in Relativistic Rotating Stars

The axial mode oscillations are examined for relativistic rotating stars with uniform angular velocity. Using the slow rotation formalism and the Cowling approximation, we have derived the equations

Relativistic r-Modes in Slowly Rotating Neutron Stars: Numerical Analysis in the Cowling Approximation

We investigate the properties of relativistic r-modes of slowly rotating neutron stars by using a relativistic version of the Cowling approximation. In our formalism, we take into account the

Rotational Modes of Nonisentropic Stars and the Gravitational Radiation-driven Instability

We investigate the properties of the r-mode and the inertial mode of slowly rotating, nonisentropic, Newtonian stars by taking account of the effects of the Coriolis force and the centrifugal force.

Results on the spectrum of r-modes of slowly rotating, relativistic stars

The paper considers the spectrum of axial perturbations (‘pure r-modes’) of slowly uniformly rotating, general relativistic stars. In a first step towards a full analysis, we analyse the evolution

Nonlinear evolution of r-modes: The role of differential rotation

Recent work has shown that differential rotation, producing large scale drifts of fluid elements along stellar latitudes, is an unavoidable feature of r-modes in the nonlinear theory. We investigate

We consider both mode calculations and time-evolutions of axial r modes for relativistic uniformly rotating non-barotropic neutron stars, using the slow-rotation formalism, in which rotational

Inertial Modes of Slowly Rotating Isentropic Stars

We investigate inertial mode oscillations of slowly and uniformly rotating, isentropic, Newtonian stars. Inertial mode oscillations are induced by the Coriolis force due to the star's rotation, and

r modes and mutual friction in rapidly rotating superfluid neutron stars

We develop a new perturbative framework for studying the r modes of rotating superfluid neutron stars. Our analysis accounts for the centrifugal deformation of the star, and considers the two-fluid
