Abstract
The measurement of for PSR J1614-2230 and for PSR J0348 + 0432 puts a strong constraint on the neutron star equation of state and its exotic composition at higher densities. In this paper, we investigate the possibility of an exotic equation of state within the observational mass constraint of in the framework of relativistic mean field model with density-dependent couplings. We particularly study the effect of antikaon condensates in the presence of hyperons on the mass-radius relationship of the neutron star.
