Many interesting terrestrial and astrophysical scenarios involving magnetic fields can be approached in axial geometry. Even though the Lagrangian smoothed particle hydrodynamics (SPH) technique has been successfully extended to handle magneto-hydrodynamic (MHD) problems, a well-verified, axisymmetric MHD scheme based on the SPH technique does not exist. In this work, we propose and check a new axisymmetric MHD hydrodynamic code that can be applied to astrophysical and engineering problems which display an adequate geometry. We show that a hydrodynamic code built on these axisymmetric premises is able to produce similar results to standard 3D-SPHMHD codes but with much lesser computational effort.

  1. An energy approach to pulsar-disc interaction: disc stability and implications for transitional millisecond pulsars

    astro-ph.HE 2025-05 conditional novelty 5.0 of 10

    Axisymmetric SPH-MHD simulations show accretion discs around oblique millisecond pulsars are disrupted when the inner disc radius lies well beyond the light cylinder, confirming the Ekşi and Alpar stability diagram.
