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…
Attractive and repulsive Yang-Mills--Higgs magnetic monopoles on
Francisco Navarro-Lérida, Eugen Radu, D. H. Tchrakian
An -gauged Higgs model on is proposed that, like the Abelian Higgs model on , features both attractive and repulsive phases, though unlike the l…
Multipolar Proca stars: electric, magnetic and hybrid solitons
Carlos Herdeiro, Eugen Radu, Etevaldo dos Santos Costa Filho +1
We construct new families of everywhere regular, asymptotically flat solitons in the Einstein--Proca model, obtained as self-gravitating continuations of flat-spacetime (singular)…
Spinning extremal dyonic black holes in Einstein-Maxwell-dilaton theory
Jose Luis Blázquez-Salcedo, Carlos Herdeiro, Eugen Radu +2
We propose a general framework for the study of asymptotically flat spinning dyonic {\it extremal} black holes (eBHs) in Einstein-Maxwell-dilaton theory. Restricting to the s…
Charged, rotating black holes in Einstein-Maxwell-dilaton theory
Carlos Herdeiro, Eugen Radu, Etevaldo dos Santos Costa Filho
The asymptotically flat, electrically charged, rotating black holes (BHs) in Einstein-Maxwell-dilaton (EMd) theory are known in closed form for \textit{only} two particular values…
Stability and collisions of excited spherical boson stars: glimpses of chains and rings
Marco Brito, Carlos Herdeiro, Eugen Radu +2
Scalar, spherically symmetric, radially excited boson stars were previously shown to be stabilized, against spherical dynamics, by sufficiently strong self-interactions. Here, we f…
Eccentric mergers of binary Proca stars
Gabriele Palloni, Nicolas Sanchis-Gual, José A. Font +2
We present a numerical relativity study of eccentric mergers of equal-mass rotating Proca stars, focusing on their gravitational-wave (GW) emission. By systematically va…
Reissner-Nordström dyonic black holes with gauged scalar hair
Carlos Herdeiro, Eugen Radu, Yakov Shnir
For gauged scalar fields minimally coupled to Einstein-Maxwell theory, the Mayo-Bekenstein no-hair theorem can be circumvented when including appropriate scalar self-interactions,…
Spinning Proca-Higgs balls, stars and hairy black holes
Carlos Herdeiro, Eugen Radu, Etevaldo dos Santos Costa Filho
Recently, spherical and static flat space solitons (balls) and self-gravitating, everywhere regular, asymptotically flat solitons (stars) were constructed in an Einstein-Proca-Higg…
The non-spherical ground state of Proca stars
C. A. R. Herdeiro, E. Radu, N. Sanchis-Gual +2
Spherical Proca Stars (PSs) are regarded as the ground state amongst the family of PSs. In accordance, spherical PSs are thought to have a fundamental branch of stable solutions. I…
Spinning gauged boson and Dirac stars: a comparative study
Carlos Herdeiro, Ilya Perapechka, Eugen Radu +1
Scalar boson stars and Dirac stars are solitonic solutions of the Einstein{Klein-Gordon and Einstein- Dirac classical equations, respectively. Despite the different bosonic vs: fer…
