The authors' main claim We propose herein a scenario for a collision between a neutron star (NS) and a white dwarf (WD) as the progenitor of the FRBs by considering the burst duration scaling to the collision time and the radio luminosity proportional to the kinetic energy of the collision.

Fast radio bursts (FRBs) with unknown origin emit a huge luminosity (about 1 Jy at 1 GHz) with a duration of milliseconds or less at extragalactic distances estimated from their large dispersion measure (DM). We propose herein a scenario for a collision between a neutron star (NS) and a white dwarf (WD) as the progenitor of the FRBs by considering the burst duration scaling to the collision time and the radio luminosity proportional to the kinetic energy of the collision. The relations among the observed flux density, pulse width, and the DM are derived from the model and compared with the statistical results from the observed FRBs. Although the sample is quite small, we tentatively report a nearly inverse-square correlation between the observed peak flux density and the DM excess, which is an consequence of the assumption that the DM excess (i.e. that not due to our Galaxy) is dominated by the intergalactic medium. We also tentatively note a correlation among the duration of the FRB and the DM excess (possibly interpreted as due to the broadening of the signal in the intergalactic medium) and a correlation among the duration of the FRB and the flux density (shorter burst should be brighter), both roughly in agreement with the proposed model.

Merging compact objects have been hypothesised to produce FRBs through magnetic interaction between the two bodies in the system, including binary neutron star systems [ref] , black hole-neutron star systems [ref] , and white dwarfs (WD) with either a neutron star or a black hole [ref] .

The origin of FRBs still remains unclear, but a number of models trying to interpret these enigma phenomena have been proposed, e.g., magnetar giant flares [ref] , the collapses of magnetized supramassive rotating neutron stars [ref] , binary neutron star mergers [ref] , binary white dwarf mergers [ref] , collisions between neutron stars and asteroids/comets [ref] , collisions between neutron stars and white dwarfs [ref] , and evaporation of primordial black holes [ref] .
