    "abstract": "The possibility of formation of a droplet phase (DP) inside a star and its\nconsequences on the structural properties of the star are investigated. For\nnuclear matter (NM), an equation of state (EOS) based on finite range, momentum\nand density dependent interaction, and which predicts that neutron matter\nundergoes ferromagnetic transition at densities realisable inside the neutron\nstar is employed. An EOS for quark matter (QM) with density dependent quark\nmasses, the so-called effective mass model, is constructed by correctly\ntreating the quark chemical potentials. It is then found that a droplet phase\nconsisting of strange quark matter and unpolarised nuclear matter sandwiched\nbetween a core of polarised nuclear matter and a crust containing unpolarised\nnuclear matter exists. Moreover, we could explain the mass and surface magnetic\nfield satisfactorily, and as well allow, due to the presence of a droplet\nphase, the direct URCA process to happen.",
