摘要：
Einstein gravity supplemented by a scalar field nonminimally coupled to a Gauss-Bonnet term provides an example of model of scalar-tensor gravity where hairy black holes do exist. We consider the classical equations within a metric endowed with a NUT-charge and obtain a two-parameter family of nutty-hairy black holes. The pattern of these solutions in the exterior and the interior of their horizon is studied in some details. The influence of both - the hairs and the NUT-charge - on the lightlike and timelike geodesics is emphasized.
