Moment of inertia, quadrupole moment, Love number of neutron star and their relations with strange matter equations of state

We investigate the impact of strange matter equations of state involving $\mathrm{\Lambda }$ hyperons, Bose-Einstein condensate of $K^{-}$ mesons and first order hadron-quark phase transition on moment of inertia, quadrupole moment and tidal deformability parameter of slowly rotating neutron stars. All these equations of state are compatible with the 2 M${}_{solar}$ constraint. The main findings of this investigation are the universality of the I-Q and I-Love number relations, which are preserved by the EoSs including $\mathrm{\Lambda }$ hyperons and antikaon condensates, but broken in presence of a first order hadron-quark phase transition. Furthermore, it is also noted that the quadrupole moment approaches the Kerr value of a black hole for maximum mass neutron stars.
