A broader description, observational effects and detailed information.
This is an FRB model where the merger of two neutron stars would lead to the generation of an isotropic radio pulse.

In general this model would predict that FRBs arise from old stellar populations where NS-NS binary systems have had time to form and evolve into compact orbits.
FRBs from magnetars born in NS-NS mergers and accretion induced WD collapse will be accompanied by persistent synchrotron radio emissionon timescales of months to years, powered by the nebula of relativistic electrons and magnetic fields inflated by the magnetar flares, or on longer timescales through interaction of the merger ejecta with the interstellar medium;  this timescale is shorter than for the SLSN/LGRB channel.

Model Description

This model considers FRBs from magnetars born in NS-NS mergers and accretion induced WD collapse. The FRBs themselves are formed by the same mechanism as that of giant flare FRB theories.

Observational Constraints

FRBs from magnetars born in NS-NS mergers and accretion induced WD collapse will be accompanied by persistent synchrotron radio emissionon timescales of months to years, powered by the nebula of relativistic electrons and magnetic fields inflated by the magnetar flares, or on longer timescales through interaction of the merger ejecta with the interstellar medium; this timescale is shorter than for the SLSN/LGRB channel.
