| After the gravitational wave(GW)of binary black hole(BH)mergers and the grav-itational wave(GW)of binary neutron star(NS)mergers to be found,the study of dou-ble compact star mergers are put up to the frontier science of high-energy astrophysics.Especially the found of GW 170817 and the electromagnetic counterpart,not only di-rectly prove NS-NS merger to be one of the origin of short gamma-ray burst(SGRB),but also the signs of the beginning of GW and multiband electromagnetic counterparts multimessenger study.It’s a new era of astronomy.It’s a long time that SGRBs have been proposed to originate from double compact star mergers.And the unified dynamical afterglow model gave a good description of af-terglow emission.From the numerical simulation,whatever NS-NS or NS-BH system will have some dynamical ejecta.Radioactive substance is synthesized in the ejecta through r-process and supply energy to the ejecta to produce Kilonova.These electro-magnetic radiation was verified by the found of GW 170817 and the electromagnetic counterparts.Fast radio burst(FRB)serve as a young high-energy astrophysic transient phe-nomena,the burst mechanism is not clare by now.The time scale of FRBs is extremely short～ms,but the flux density is extremely high～Jy ms.It is easily to be associated with the origination of compact star and come up with many models to explain FRBs.The scientists made great efforts to search the electromagnetic counterparts of FRBs.FRB 150814 used to be considered that there were electromagnetic counterparts found from 2 hours to 6 days after the burst at 5.5 GHz and 7.5 GHz.But denied by sub-sequently observation soon.The observations suggested that the radio emission was come from active galactic nucleus(AGN).So the first attempt to find electromagnetic counterparts of FRBs was field.While FRB 131104/Swift J0644.5-5111 associated GRBs with FRBs.Although there showed to have AGN as well,the possibility of FRB 131104/Swift J0644.5-5111 have the same origin is not excluded.In this thesis,we mainly discussed the possibility of the correlation of compact binary mergers with FRBs.In the first chapter,we gave an outline of multiband elec-tromagnetic radiation from compact binary merger.In the second chapter,we intro-duce the classify of FRBs,and mainly divide into non-repeat FRBs and repeat FRBs.We emphatically introduce the models of NS-NS merger and NS-BH merger to create FRBs.In the third chapter,we used the unified dynamical afterglow model to study the environmental Properties of FRB 131104/Swift J0644.5-5 111 event.But we field to find other band counterparts except gamma-ray,so we could only Constrain the en-vironmental Properties of FRB 131104 with the up limit of each detector.And we put forward that FRB 131104 might originated from BH-NS merger event.The last chapter,we present a brief summary and outlook of compact binary mergers. |
