本文提出了一个简化的磁化中微子主导吸积流模型,该模型采用一组相对论修正因子,考虑了黑洞自旋的影响,并将磁场参数化为磁压与总压之比β。结果表明,盘的性质对BH自旋和β值敏感,更快的自旋和更低的β值可以从NDAF中提取更多的能量.
In this paper, we present a simplified model for a magnetized neutrino-dominated accretion flow (NDAF) in which the effect of black hole (BH) spin is taken into account by adopting a set of relativistic correction factors, and the magnetic field is parameterized asβ, the ratio of the magnetic pressure to the total pressure. It is found that the disc properties are sensitive to the values of the BH spin andβ, and more energy can be extracted from NDAFs by using a faster spin and lowerβ.
