  We investigate gross properties of binary components and remnant in GW170817
using equations of state within the finite temperature field theoretical
models. We also adopt finite temperature equations of state in the density
dependent hadron field theory for this study. Properties of binary components
are studied using zero temperature equations of state. Particularly, we
investigate tidal deformabilities and radii of binary components in light of
GW170817. An analytical expression relating the radii and the combined tidal
deformability 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 tidal
deformability 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 this
case, we investigate the gravitational and baryon mass, radius, Kepler
frequency and moment of inertia of the rigidly rotating remnant for different
equations of state at fixed entropy per baryon. The remnant radius is enlarged
due to thermal effects compared with the zero temperature case. Consequently,
it is found that the Kepler frequency is much lower at higher entropy per
baryon than that of the case at zero temperature. These findings are consistent
with the results found in the literature.
