The theoretical model proposed in the study describes the structuring of a relativistic jet propagating through the ejecta of a binary neutron star merger event, taking into account the effects of neutron conversion-diffusion. This results in an increased baryon load structure of the outer jet with an energy distribution proportional to the off-axis angle.
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(theta) proportional to theta (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.
