Contribution

It presents novel black hole solutions in Lovelock gravity that incorporate anisotropic fluids extending to infinity, with distinct thermodynamic properties.

Findings

Horizon locations differ from known solutions

Temperatures and entropies are different despite same masses

Solutions extend known black hole geometries at infinity

Abstract

In this work a new family of black hole solutions in Lovelock gravity is discussed. These solutions describe anisotropic fluids which extend to the spatial infinity. Though far from the horizon their geometries approach some previously known black holes solutions the location of the horizons differ. Furthemore, although the masses of these solutions match the masses of those previously known black holes, their temperatures and entropies differ.
