Hyperon bulk viscosity effects in neutron-star inspirals
Elena M. Kantor, Mikhail E. Gusakov, Kirill Y. Kraav
The paper revisits the role of hyperon bulk viscosity during neutron-star inspiral. We find that hyperon bulk viscosity exerts only a minor influence on the gravitational-wave phas…
Beyond the Tayler instability: A new global instability of toroidal magnetic fields in stars
Mikhail E. Gusakov, Laura Becerra, Elena M. Kantor +2
Stellar toroidal magnetic fields are known to be unstable to the Tayler instability. Here we demonstrate the existence of a complementary current-driven instability of essentially…
Instability windows of relativistic r-modes in stably stratified neutron stars with hyperonic cores
K. Y. Kraav, M. E. Gusakov, E. M. Kantor
(abridged) -modes are oscillations in rotating stars, primarily restored by the Coriolis force. These oscillations are the most susceptible to the Chandrasekhar-Friedman-Schutz…
Magnetothermal evolution of neutron star cores in the `weak-coupling' regime: implications of ambipolar diffusion for the quiescent X-ray luminosity of magnetars
N. A. Moraga, F. Castillo, D. D. Ofengeim +5
The high quiescent X-ray luminosity observed in some magnetars is widely attributed to the decay and evolution of their ultra-strong magnetic fields. Several dissipation mechanisms…
Role of particle diffusion in shaping the gravitational wave signal from neutron star inspirals
Elena M. Kantor, Mikhail E. Gusakov, Kirill Y. Kraav
It is commonly believed that the dissipative properties of superdense matter play a negligible role in modeling gravitational waveforms from neutron star inspirals. This study aims…
Instability windows of relativistic r-modes
Kirill Y. Kraav, Mikhail E. Gusakov, Elena M. Kantor
The detectability of the gravitational-wave signal from -modes depends on the interplay between the amplification of the mode by the CFS instability and its damping due to dissi…
