Title |
Gravitational Wave Signals from Superfluid Turbulence in Neutron Stars | |||||

Abstract |
The nature and coupling of the multiple superfluid components inside a neutron star are reviewed. It is argued that the superfluid supports turbulent vorticity on macroscopic (Kolmogorov) and microscopic (vortex tangle) scales. Three kinds of gravitational wave signals generated by the turbulent vorticity are identified: (1) broadband bursts coinciding with rotational glitches, (2) a stochastic background due to steady-state turbulence, and (3) long-time-scale (days to weeks) continuous-wave transients during the glitch relaxation phase. Detection of such signals offers an outstanding opportunity to probe the fundamental physics of the strong nuclear force (e.g. compressibility, viscosity) in the many-body, MeV regime under conditions which cannot be replicated on Earth. |
