Abstract

Tidal deformability parameter λ of a neutron star describes quadrupole moment of neutron star due to external gravitational field is described by tidal deformability parameter. In this work, we calculate λ in binary neutron stars within relativistic mean field model. λ depends on love number k2. The dominant contribution in kl where l = 2, 3,. comes from the one of l = 2. It is expected that these kl depend quite sensitively on equation of states of neutron star core. We use TM1 parameter set to calculate the equation of state of neutron star core and investigate the effects of the hyperon coupling constant prescriptions of the corresponding parameter set i.e., the ones of SU(6) and HX1 on kl and λ. We have found that kl and λ are insensitive in respect to the hyperon coupling constant variation.
