  Dark energy stars research is an issue of great interest since recent
astronomical observations with respect to measurements in distant supernovas,
cosmic microwave background and weak gravitational lensing confirm that the
universe is undergoing a phase of accelerated expansion and this cosmological
behavior is caused by the presence of a cosmic fluid which has a strong
negative pressure that allows to explain the expanding universe. In this paper,
we obtained new relativistic stellar configurations within the framework of
Einstein-Gauss-Bonnet (EGB) gravity considering negative anisotropic pressures
and the equation of state pr={\omega}\r{ho} where pr is the radial pressure,
{\omega} is the dark energy parameter, and \r{ho} is the dark energy density.
We have chosen a modified version of metric potential proposed by
Korkina-Orlyanskii (1991). For the new solutions we checked that the radial
pressure, metric coefficients, energy density and anisotropy are well defined
and are regular in the interior of the star and are dependent of the values of
the Gauss-Bonnet coupling constant. The solutions found can be used in the
development of dark energy stars models satisfying all physical acceptability
conditions, but the causality condition and strong energy condition cannot be
satisfied.
