A Neutron Star with a Strange Quark Star-like Mass-Radius Relation
  We study the structure of spherically symmetric and static objects in the
presence of a nonminimally coupled scalar field having a potential of the form
$V(\phi)=-\mu^2\phi^2/2+\lambda\phi^4/4$. We numerically solve equations of the
system using two different realistic equations of state for neutron matter and
give the mass-radius relations as well as the radial profiles of the scalar
field, densities and the mass function for a sample configuration. We show that
a specific solution type encountered in such systems causes characteristic
neutron star mass-radius relations to turn into the ones belonging to strange
quark stars.
