Dark matter compression can trigger quark cores in unusually light neutron stars while leaving the mass-radius relation unchanged, producing 'masquerading hybrid stars' and, for light strongly interacting dark matter, 'dark oysters' with huge dark matter halos.

abstract
A new relation between the neutron skin of a heavy nucleus and the radius of a neutron star is proposed: the larger the neutron skin of the nucleus the larger the radius of the star. Relativistic models that reproduce a variety of ground-state observables can not determine uniquely the neutron skin of a heavy nucleus. Thus, a large range of neutron skins is generated by supplementing the models with nonlinear couplings between isoscalar and isovector mesons. We illustrate how the correlation between the neutron skin and the radius of the star can be used to place important constraints on the equation of state and how it may help elucidate the existence of a phase transition in the interior of the neutron star.

Masquerading hybrid stars with dark matter
Dark matter compression can trigger quark cores in unusually light neutron stars while leaving the mass-radius relation unchanged, producing 'masquerading hybrid stars' and, for light strongly interacting dark matter, 'dark oysters' with huge dark matter halos.
