The strong magnetic field of neutron stars is intimately coupled to the observed temperature and spectral properties, as well as to the observed timing properties (distribution of spin periods and period derivatives). Thus, a proper theoretical and numerical study of the magnetic field evolution equations, supplemented with detailed calculations of microphysical properties (heat and electrical conductivity, neutrino emission rates) is crucial to understand how the strength and topology of the magnetic field vary as a function of age, which in turn is the key to decipher the physical processes behind the varied neutron star phenomenology. In this review, we go through the basic theory describing the magneto-thermal evolution models of neutron stars, focusing on numerical techniques, and providing a battery of benchmark tests to be used as a reference for present and future code developments. We summarize well-known results from axisymmetric cases, give a new look at the latest 3D advances, and present an overview of the expectations for the field in the coming years.

  1. Magnetic Field Configurations in Binary Neutron Star Mergers II: Inspiral, Merger and Ejecta

    astro-ph.HE 2025-08 conditional novelty 6.0 of 10

    Initial magnetic field topology, especially anti-aligned poloidal fields, strongly controls post-merger field amplification and ejecta magnetisation in neutron star merger simulations.

  2. Ferromagnetic instabilities in quarkyonic matter

    nucl-th 2025-07 conditional novelty 6.0 of 10

    Quarkyonic neutron matter can turn ferromagnetic below about 5.5 n0, but only with a hand-chosen negative spin-spin interaction constant.

  3. Gamma Rays from ALP-Photon Conversion and Inverse Compton Reprocessing in Neutron Star Magnetospheres

    astro-ph.HE 2026-08 conditional novelty 5.0 of 10

    ALP-to-photon conversion near four pulsars produces mostly sub-MeV emission: Fermi-LAT is insensitive to the channel, COMPTEL data already exclude new parameter space at high ALP mass, and COSI could probe much more.

  4. On Ultra-long Period (53.8 min) Pulsar ASKAP J1935+2148: Coherent Radio Emission Triggered by Local Superstrong Magnetic Reconnection

    astro-ph.HE 2025-08 conditional novelty 5.0 of 10

    Ultra-long period pulsars may be Crab-like pulsars spun down by particle winds, with their radio emission powered by local magnetic reconnection instead of rotation.
