论文摘要
我们为最近发现的无线电源GLEAM-X J162759.5-523504.3提出了一个进攻性瞬态磁铁模型。我们将观察到的$ \ sim 1 $ ks的周期确定为磁体变形的进程，这是由于其强（$ b_Dcartion \ sim 10^{16} $ g）圆环字段而变形。订单$ 10^{ - 4} $的结果变形意味着$ p _ {\ rm s} = 0.1 $ s的自旋周期。假设$ b _ {\ rm d} \ sim 10^{14} $ g的强偶极场我们预测$ \ dot {p} _ {\ rm s} \ sim 10^{ - 11} $ s/s的周期衍生物。我们还预测，在硬X射线带中可以观察到磁力的进动期，就像其他三个银河磁铁表现出进攻一样。
We propose a precessing transient magnetar model for the recently discovered radio source GLEAM-X J162759.5-523504.3. We identify the observed period of $\sim 1$ ks as the precession period of the magnetar deformed due to its strong ($B_ϕ \sim 10^{16}$ G) toroidal field. The resulting deformation of order $10^{-4}$ implies a spin period of $P_{\rm s} = 0.1$ s. Assuming a strong dipole field of $B_{\rm d} \sim 10^{14}$ G we predict a period derivative of $\dot{P}_{\rm s}\sim 10^{-11}$ s/s. We also predict that the precession period of the magnetar can be observed in the hard X-ray band just as the other three galactic magnetars exhibit precession.
