A post-hypercritical accretion small-scale dynamo in newborn neutron stars — E8 Intelligence Research
Year: 2026
Type: preprint
Abstract: Hypercritical fallback accretion can advect the surface magnetic field of a newborn neutron star into the newly accreted outer layers. Before this material joins the solid crust and enters the Hall-Ohmic regime, part of it may remain hot, dense, and liquid. This short-lived fluid stage may support turbulent magnetic amplification. We test whether a small-scale dynamo (SSD) can be activated under thermodynamic conditions of the liquid post-hypercritical layer. We quantify the associated growth rates, amplification factors, and saturation levels, adopting a matter density ρ0=1010 g cm−3 and a temperature T0= Author: Andrew Stewart Caldin, Independent Researcher, UK.
