  Recently it has been proposed that the Gauss-Bonnet coupling parameter of
Lovelock gravity may suitably be rescaled in order to admit physically viable
models of celestial phenomena such that higher curvature effects are active in
standard four dimensions as opposed to the usual higher dimensions. We
investigate the consequences of this modification in the context of stellar
modelling. The evolution of perfect fluid distributions is governed by the
pressure isotropy condition and through stipulation of one of the metric
potentials complete models emerge from solutions of the master differential
equation. New classes of exact solution with this approach have been reported.
One particular model is analysed in detail and shown to comport with elementary
physical requirements demanded of realistic compact stars suggesting that the
modified theory is not inconsistent with observations.
