Neutron diffusion in magnetars as a source of astrophysical bursts

Abstract Neutron tunneling in neutron star crusts can release enormous amounts of energy on a short timescale. We have clarified aspects this process occurring the outer crust regions stars when oscillations or cataclysmic events changes crustal ambient density. report time-dependent Hartree-Fock-Bogoliubov model to determine rate diffusion and conclude that large amount energy, range ∼ 10 40 – 44 erg, be released rapidly. suggest mechanism may source hitherto unknown phenomena such as Fast Radio Bursts (FRBS).
