Neutron star merger event GW170817 puts strong constraints on the
dense matter equation of state (EoS). A comparative study of finite temper-
ature dense matter EoSs used widely in core collapse supernova and neutron
star merger simulations is presented here with special emphasis on the Λ
hyperon EoS, BHBΛφ, constructed by Banik, Hempel & Bandyopadhyay.
Moment of inertia of merger components of GW170817 is also discussed in
this context.
