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…
