论文摘要
我们提出了一个通用的理论模型，用于通过二进制中子星合并事件的弹射射流的相对论射流的结构化，从而引入了中子转化 - 扩散的效果，中子转化 - 扩散的效果可提供从射流横向向射流轴的横向传播的baryon通量。这自然会导致外部喷气机的重骨负荷结构，并具有近似的各向同性能量分布$ e_ {iso}（θ）\ proptoθ^{ - 4} $，这与第一个引力波和短伽玛射线爆发事件GW170817/GRB 170817A AT a Off-aid oft-aid od-jut at-ip at of-aid at of-aid apent of-jut at of-jut at of-aid aid apy aid apy aid of-aid aid of-ip a part of-aid aid of-aid at-ip a party of-aid aid op of-jut。
We present a generic theoretical model for the structuring of a relativistic jet propagating through the ejecta of a binary neutron star merger event, introducing the effects of the neutron conversion-diffusion, which provides a baryon flux propagating transversely from the ejecta towards the jet axis. This results naturally in an increased baryon load structure of the outer jet with the approximate isotropic energy distribution $E_{iso}(θ) \propto θ^{-4}$, which is compatible with the first gravitational wave and short gamma-ray burst event GW170817/GRB 170817A observed at an off-axis angle of the jet.
