| « Static and asymptotically flat black holes in Horndeski theory » |
|
Antoine Lehébel |

A no-hair theorem for black holes was formulated for Horndeski
theory with a shift-symmetric scalar field. However, the theorem relies on many assumptions, and many hairy solutions exist accordingly. I will review the existing way outs and explore some new possibilities, with the corresponding hairy solutions. These include the first analytic, asymptotically flat and static solution, some “stealth” Schwarzschild black holes, and a linear coupling between the scalar and the Gauss-Bonnet invariant. |
