# A Toy Model for Magnetized Neutrino-Dominated Accretion Flows - Astrophysics > High Energy Astrophysical Phenomena

Abstract: In this paper, we present a simplified model for magnetizedneutrino-dominated accretion flow NDAF in which effect of black hole BHspin is taken into account by adopting a set of relativistic correction factor,and the magnetic field is parameterized as \beta, the ratio of the magneticpressure to the total pressure. It is found that the disc properties aresensitive to the values of the BH spin and \beta, and more energy can beextracted from NDAF for the faster spin and lower \beta.
