| Talk Title |
Self-interacting scalar hair around Kerr black holes |
|
Abstract |
In this talk, I will discuss families of asymptotically flat, rotating black holes with self-interacting scalar hair and a regular horizon, within the framework of four dimensional general relativity coupled to a complex, massive scalar field. When the self-interaction vanishes, these solutions reduce to the Kerr black holes with scalar hair (KBHsSH) found by Herdeiro et al (2014). These solutions interpolate continuously between the corresponding family of boson stars, for a vanishing horizon, and a subset of vacuum Kerr black hole, as the scalar field vanishes. These new families of solutions are supported by rotation, have no static limit and are described by their mass, angular momenta and conserved Noether charge. Here, I will consider both a quartic self-interaction potential. I will look for the maximal possible mass of those hairy black holes and why this quantity is important in astrophysical scenarios. |
