费米子零模对中子星磁场演化的影响

Fermion zero-mode influence on neutron-star magnetic field evolution

P. B. Jones

摘要:

在实验室超流体(如3 He-B)中观察到的谱流量子现象控制着中子星液核中质子II型超导体涡旋的漂移速度,从而决定了磁通量从核中排出到地壳的速率。在最早期和最活跃的阶段,异常X射线源和软伽马中继器的速率很低,与大部分活跃的地壳通量不连接的核心一致。如果正常的中子存在于一个可观的核心物质密度区间,在快速自旋下降的情况下,如在蟹状星云脉冲星或在推进器阶段的二元系统的频谱流力限制通量驱逐。

英文摘要:

The quantum phenomenon of spectral flow which has been observed in laboratory superfluids, such as 3He-B, controls the drift velocity of proton type II superconductor vortices in the liquid core of a neutron star and so determines the rate at which magnetic flux can be expelled from the core to the crust. In the earliest and most active phases of the anomalous X-ray pulsars and soft-gamma repeaters, the rates are low and consistent with a large fraction of the active crustal flux not linking the core. If normal neutrons are present in an appreciable core matter-density interval, the spectral flow force limits flux expulsion in cases of rapid spin-down, such as in the Crab pulsar or in the propeller phase of binary systems.
