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…
