Magnetar magnetothermal evolution with Landau-quantized electrons: enhanced Joule heating due to free electron diamagnetism and the magnetar heating problem
Peter B. Rau
Magnetars are systematically more luminous than other neutron stars. Previous studies suggest that supporting such high luminosities requires a heat source beyond standard Ohmic di…
Numerical simulation of electron magnetohydrodynamics with Landau-quantized electrons in magnetar crusts
Peter B. Rau, Ira Wasserman
In magnetar crusts, magnetic fields are sufficiently strong to confine electrons into a small to moderate number of quantized Landau levels. This can have a dramatic effect on the…
Josephson currents in neutron stars
Armen Sedrakian, Peter B. Rau
We demonstrate that the interface between -wave and -wave paired superfluids in neutron stars induces a neutron supercurrent, a charge-neutral analog of the Josephson junctio…
Two first-order phase transitions in hybrid compact stars: higher-order multiplet stars, reaction modes and intermediate conversion speeds
Peter B. Rau, Armen Sedrakian
We study compact stars with hybrid equations of state consisting of a nuclear outer region and two nested quark phases, each separated from the lower density phase by a strong firs…
Magnetohydrodynamic stability of magnetars in the ultrastrong field regime II: The crust
Peter B. Rau, Ira Wasserman
We study the stability of Hall MHD with strong magnetic fields in which Landau quantization of electrons is important. We find that the strong-field Hall modes can be destabilized…
Unstable modes of hypermassive compact stars driven by viscosity and gravitational radiation
Peter B. Rau, Armen Sedrakian
We study the oscillations modes of differential rotating remnants of binary neutron star inspirals by modeling them as incompressible Riemann ellipsoids parametrized by the ratio $…
Magnetohydrodynamic stability of magnetars in the ultrastrong field regime I: The core
Peter B. Rau, Ira Wasserman
We study magnetohydrodynamic stability of neutron star core matter composed of neutrons, protons and leptons threaded by a magnetar-strength magnetic field -- G,…
Oscillations of hypermassive compact stars with gravitational radiation and viscosity
Peter B. Rau, Armen Sedrakian
Binary neutron star mergers, such as the multimessenger GW170817 event, may produce hypermassive compact objects which are supported against collapse by the internal circulation of…
Relativistic finite temperature multifluid hydrodynamics in a neutron star from a variational principle
Peter B. Rau, Ira Wasserman
We develop a relativistic multifluid dynamics appropriate for describing neutron star cores at finite temperatures based on Carter's convective variational procedure. The model inc…
Compressional modes in two-superfluid neutron stars with leptonic buoyancy
P. B. Rau, I. Wasserman
We investigate the compressional modes of cold neutron stars with cores consisting of superfluid neutrons, superconducting protons and normal fluid electrons and muons, and crusts…
