Two asymptotically flat spinning black holes balanced by their self-interacting, synchronised scalar hair
Chen Liang, Carlos Herdeiro, Eugen Radu
Asymptotically flat balanced configurations of two spinning black holes with synchronised scalar hair (2sBHs) are possible (arXiv:2305.15467). These are constructed within a genera…

Bifurcations in Bosonic Stars: chains and rings from spherical solutions
Chen Liang, Carlos A. R. Herdeiro, Eugen Radu
We study the bifurcation phenomena between spherical and axisymmetric bosonic stars. By numerically solving for the zero-modes of spherical bosonic stars under specific axially sym…
