Scientific paper

In a superhigh magnetic field, direct Urca reactions can proceed for an arbitrary proton concentration. Since only the electrons with high energy E ( E> Q, Q is the threshold energy of inverse β-decay) at large Landau levels can be captured, we introduce the Landau level effect coefficient q and the effective electron capture rate Γ eff . By using Γ eff , the values of L X and L ν are calculated, where L X and L ν are the average neutrino luminosity of AXPs and the average X-ray luminosity of AXPs L X , respectively. The complete process of electron capture inside a magnetar is simulated numerically.
