We investigate gross properties of binary components and remnant in GW170817using equations of state within the finite temperature field theoreticalmodels. We also adopt finite temperature equations of state in the densitydependent hadron field theory for this study. Properties of binary componentsare studied using zero temperature equations of state. Particularly, weinvestigate tidal deformabilities and radii of binary components in light ofGW170817. An analytical expression relating the radii and the combined tidaldeformability is obtained for binary neutron star masses in the range$1.1M_{\odot}\lesssim M\lesssim 1.6 M_{\odot}$. The upper bound on the tidaldeformability gives the upper bound on the neutron star radius as 13 km. Next,the role of finite temperature on the remnant in GW170817 is explored. In thiscase, we investigate the gravitational and baryon mass, radius, Keplerfrequency and moment of inertia of the rigidly rotating remnant for differentequations of state at fixed entropy per baryon. The remnant radius is enlargeddue to thermal effects compared with the zero temperature case. Consequently,it is found that the Kepler frequency is much lower at higher entropy perbaryon than that of the case at zero temperature. These findings are consistentwith the results found in the literature.
