Numerical simulation of the electron capture process in a magnetar interior

In a superhigh magnetic field, direct Urea 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 beta-decay) at large Landau levels can be captured, we introduce the Landau level effect coefficient q and the effective electron capture rate Gamma(eff). By using Gamma(eff), the values of L-X and L-nu are calculated, where L-X and L-nu, 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.
