Abstract

We uncover two mechanisms that can render Kerr black holes unstable in scalar-tensor gravity, both associated to the presence of matter in the vicinity of the black hole and the fact that this introduces an effective mass for the scalar. Our results highlight the importance of understanding the structure of spacetime in realistic, astrophysical black holes in scalar-tensor theories.

    • Again, small caveat that to keep this close to ELI25, I am abusing some things (including changes in sign) in a way an expert will notice [they can refer to [1] where the signs and frames are dealt with carefully], but I believe this does not qualitatively affect the…
