Universal Inflationary Attractors Implications on Static Neutron Stars
  We study static neutron stars in the context of a class of non-minimally
coupled inflationary potentials, the universal attractors. Universal attractors
are known to generate a viable inflationary era, and they fall into the same
category of inflationary phenomenology as the $R^2$ model and other well-known
cosmological attractors. We present the essential features of universal
attractors in both the Einstein and Jordan frame, and we extract the
Tolman-Oppenheimer-Volkoff equations in the Einstein frame using the usual
notation of theoretical astrophysics. We use a python 3 based double shooting
numerical code for our numerical analysis and we construct the $M-R$ graphs for
the universal attractor potential, using piecewise polytropic equation of state
the small density part of which is the WFF1 or the APR or the SLy equation of
state. As we show, all the studied cases predict larger maximum masses for the
neutron stars, and all the results are compatible with the GW170817 constraints
imposed on the radii of the neutron stars.
