论文摘要
脉冲星的发射可能会在配对放电中产生，这些放电以通过新鲜创建的对筛选到加速电场时，将脉冲星磁层充满等离子体。在这封信中，我们开发了一种简化的分析理论，用于筛选这些对排放中的电场，并使用它来估计无线电的光度和频谱。排放有三个阶段。首先，首次筛选电场并开始振荡。接下来，发生非线性相。在此阶段，电场的幅度经历了强烈的阻尼，因为该场会极大地改变新创建的对的动量。当电场不再显着改变对成对动量时，这种强大的阻尼停止了，系统进入最终线性相。应用于脉冲星，该理论可以解释无线电发射的几个方面，包括观察到的光度，$ l _ {\ rm {rad}} \ sim 10^{28} \ rm {erg {erg} \，\ rm {s}
Pulsar radio emission may be generated in pair discharges which fill the pulsar magnetosphere with plasma as an accelerating electric field is screened by freshly created pairs. In this Letter we develop a simplified analytic theory for the screening of the electric field in these pair discharges and use it to estimate total radio luminosity and spectrum. The discharge has three stages. First, the electric field is screened for the first time and starts to oscillate. Next, a nonlinear phase occurs. In this phase, the amplitude of the electric field experiences strong damping because the field dramatically changes the momenta of newly created pairs. This strong damping ceases, and the system enters a final linear phase, when the electric field can no longer dramatically change pair momenta. Applied to pulsars, this theory may explain several aspects of radio emission, including the observed luminosity, $L_{\rm{rad}} \sim 10^{28} \rm{erg} \, \rm{s}^{-1}$, and the observed spectrum, $S_ω\sim ω^{-1.4 \pm 1.0} $.
