    "abstract": "We generalise the finite range momentum and density dependent\nSeyler-Blanchard nucleon-nucleon effective interaction to the case of\ninteraction between two baryons. This effective interaction is then used to\ndescribe dense hadronic matter relevant to neutron stars in the nonrelativistic\nThomas-Fermi approach. We investigate the behaviour of nuclear symmetry energy\nin dense nuclear and hyperon matter relevant to neutron stars. It is found that\nthe nuclear symmetry energy always increases with density in hyperon matter\nunlike the situation in nuclear matter. This rising characteristic of the\nsymmetry energy in presence of hyperons may have significant implications on\nthe mass-radius relationship and the cooling properties of neutron stars. We\nhave also noted that with the appearance of hyperons, the equation of state\ncalculated in this model remains causal at high density.",
