轴子团可能是快速射电暴的来源吗?

May axion clusters be sources of fast radio bursts?

Maxim S. Pshirkov

摘要:

快速射电暴可以由一些与“新物理”有关的现象引起,其中最突出的候选者是轴子玻色星,它可以在中子星的磁层中或在其坍缩过程中转化为光子时产生暴。在这篇简短的研究报告中,概述了三个观测标准的重要性,即总能量、$\mathcal{O}$(ms)持续时间和光谱的非单色形状。结果表明,这是不可能的,以满足这些标准在简化模型的轴子-中子星相互作用的情况下,更复杂的模型,涉及反反应和非线性效应的深入调查,需要在这种情况下,以解释FRB。

英文摘要:

Fast radio bursts can be caused by some phenomena related to 'new physics'.One of the most prominent candidates of the kind are axion Bose stars which can engender bursts when undergoing conversion into photons in magnetospheres of neutron stars or during their collapse. In this short research note an importance of three observational criteria is outlined, namely total energetic, $\mathcal{O}$(ms) duration and non-monochromatic shape of the spectrum. It is shown that it is impossible to meet these criteria in simplified models of axion-neutron star interaction scenario and thorough investigation of more complex models which involve back-reaction and non-linear effects are needed in order to explain FRBs within this scenario.
