Nonlinear Development of the R Mode Instability and the Maximum Rotation Rate of Neutron Stars
We describe how the nonlinear development of the R-mode instability of neutron stars influences spin up to millisecond periods via accretion. When nearly resonant interactions of the l = m = 2 R-mode with pairs of ”daughter modes” are included, the R-mode saturates at the lowest amplitude which leads to significant excitation of a pair of modes. The lower bound for this threshold amplitude is p...
متن کاملThe R-mode Instability in Rotating Neutron Stars
In this review we summarize the current understanding of the gravitational-wave driven instability associated with the so-called r-modes in rotating neutron stars. We discuss the nature of the r-modes, the detailed mechanics of the instability and its potential astrophysical significance. In particular we discuss results regarding the spin-evolution of nascent neutron stars, the detectability o...
متن کاملGravitational Waves from Spinning Neutron Stars
This paper gives an introductory overview of the search for continuous gravitational waves from spinning neutron stars. We review the current theoretical understanding of possible emission mechanisms and the expected strength of signals received on Earth. Given the substantial uncertainties involved in neutron star physics, these searches — if sufficiently sensitive — can provide important new ...
متن کاملNonaxisymmetric Magnetorotational Instability in Proto-Neutron Stars
We investigate the stability of differentially rotating proto-neutron stars (PNSs) with a toroidal magnetic field. Stability criteria for nonaxisymmetric MHD instabilities are derived using a local linear analysis. PNSs are expected to have much stronger radial shear in the rotation velocity compared to normal stars. We find that nonaxisymmetric magnetorotational instability (NMRI) with a large...
متن کاملNew instability windows for rotating neutron stars
We reanalyze the r-mode instability in rotating superfluid neutron stars. To this aim we develop a model of resonance interaction of normal m = 2 r-mode with superfluid modes. We show that this interaction dramatically modifies the instability window, that is the region of stellar spin frequencies and temperatures in which a neutron star becomes unstable with respect to radiation of gravitation...
