Magnetic fields in upper main-sequence stars, white dwarfs, and neutron stars are known to persist for timescales comparable to their lifetimes. From a theoretical perspective this is problematic, as it can be shown that simple magnetic field configurations are always unstable. In non-barotropic stars, stable stratification allows for a much wider range of magnetic field structures than in barotropic stars, and helps stabilize them by making it harder to induce radial displacements.

Upper main-sequence stars, white dwarfs, and neutron stars are known to possess stable, large-scale magnetic fields. Numerical works have confirmed that stable magnetohydrodynamic equilibria can
Magnetic field configurations in neutron stars from MHD simulations
We have studied numerically the evolution of magnetic fields in barotropic neutron stars, by performing nonlinear magnetohydrodynamical simulations with the code PLUTO. For both initially

Abstract The strongest known magnetic fields are found in neutron stars. I briefly discuss how they are inferred from observations, as well as the evidence for their time-evolution. I go on to show
Instability of magnetic equilibria in barotropic stars
ABSTRACT In stably stratified stars, numerical magneto-hydrodynamics simulations have shownthat arbitrary initial magnetic fields evolve into stable equilibrium configurations,usually containing nearly
Stability of toroidal magnetic fields in stellar interiors
We present 3D MHD simulations of purely toroidal and mixed poloidal-toroidal magnetic field configurations to study the behavior of the Tayler instability. For the first time the simultaneous action
Stability Analysis of Magnetised Neutron Stars - A Semi-analytic Approach
We implement a semi-analytic approach for stability analysis, addressing the ongoing uncertainty about stability and structure of neutron star magnetic fields. Applying the energy variational
Magnetic fields driven by tidal mixing in radiative stars
Stellar magnetism plays an important role in stellar evolution theory. Approximatively 10  per cent of observed main sequence (MS) and pre-main-sequence (PMS) radiative stars exhibit surface magnetic
Neutron star deformation due to poloidal-toroidal magnetic fields of arbitrary multipole order: a new analytic approach
A recipe is presented to construct an analytic, self-consistent model of a non-barotropic neutron star with a poloidal-toroidal field of arbitrary multipole order, whose toroidal component is
Modeling of magneto-rotational stellar evolution
While magnetic fields have long been considered to be important for the evolution of magnetic non-degenerate stars and compact stars, it has become clear in recent years that actually all of the
The role of currents distribution in general relativistic equilibria of magnetized neutron stars
Magnetic fields play a critical role in the phenomenology of n eutron stars. There is virtually no observable aspect which is not governed by them. Despite this, only recently efforts have been done


Stable magnetic equilibria and their evolution in the upper main sequence, white dwarfs and neutron stars
Context. Long-lived, large-scale magnetic field configurations exist in upper main sequence, white dwarf, and neutron stars. Externally, these fields have a strong dipolar component, while their
Axisymmetric magnetic fields in stars: relative strengths of poloidal and toroidal components

Stable magnetic fields in stellar interiors
We investigate the 50-year old hypothesis that the magnetic fields of the Ap stars are stable equilibria that have survived in these stars since their formation. With numerical simulations we find

A strong candidate for a source of gravitational waves is a highly magnetized, rapidly rotating neutron star (magnetar) deformed by internal magnetic stresses. We calculate the mass quadrupole moment

Numerical simulations show that stable magnetic field configurations, with properties agreeing with those observed, can develop through evolution from arbitrary, unstable initial fields, establishing fossil fields as the natural, unifying explanation for the magnetism of all these stars.

General conditions for adiabatic instability of weak axisymmetric toroidal magnetic fields are obtained. In particular all fields which haveHϕ=0 and ∂Hϕ2/∂δ>0 simultaneously are unstable. This
