Query: An Entropy-Area Law for Neutron Stars Near the Black Hole Threshold   Neutron stars exhibit a set of universal relations independent of their
equation of state that bears semblance to the black hole no hair relations.
Motivated by this, we analytically and numerically explore other relations that
connect neutron star and black hole universality. By analyzing two different
measures, we find that certain rescaled entropies possess a nearly universal
behavior. We also discover that when the compactness of neutron stars
approaches the black hole limit, the rescaled entropy approaches that of a
black hole, and the thermodynamic entropy scales with the stellar surface area
in an ever more universal way.
