Exact dark energy star solutions
  Adopting the phantom (ghost) scalar field description of dark energy, we construct a general class of exact interior solutions describing mixed relativistic stars containing both ordinary matter and dark energy in different proportions. The exterior solution that continuously matches the interior solutions is found. Exact solutions describing extremal configuration with zero ordinary matter pressure are also constructed.
