| contents | GW170817 represents the first observed binary neutron star merger event by humanity. The observation of GW170817 has identified the correlation between Kilonova, gravitational wave and short GRB. The shocks from GW170817 have the capacity to inject significant thermal and kinetic energies into the interstellar medium and evolve for over a million years. In this letter, we adopt the special relativity fluid dynamics equations to simulate the evolution of the GW170817 remnant over a span of one million years. Our simulations yield the evolution profiles of the velocity, density, mass, radius, luminosity, and energies of the remnant. We estimate that the GW170817 remnant will reach the average maximum luminosity $ 2.56\times 10^{39}$ erg s$^{-1}$at approximately $3.96\times 10^4$ yr. At the end of the cooling stage, the contaminated radius and mass are $48.35$ pc and $2.25\times 10^4 M_{\odot}$, respectively. |
