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…
Chains of Boson Stars
C. A. R. Herdeiro, J. Kunz, I. Perapechka +2
We study axially symmetric multi-soliton solutions of a complex scalar field theory with a sextic potential, minimally coupled to Einstein's gravity. These solutions carry no angul…
Multipolar boson stars: macroscopic Bose-Einstein condensates akin to hydrogen orbitals
C. A. R. Herdeiro, J. Kunz, I. Perapechka +2
Boson stars are often described as macroscopic Bose-Einstein condensates. By accommodating large numbers of bosons in the same quantum state, they materialize macroscopically the i…
Asymptotically flat spinning scalar, Dirac and Proca stars
C. Herdeiro, I. Perapechka, E. Radu +1
Einstein's gravity minimally coupled to free, massive, classical fundamental fields admits particle-like solutions. These are asymptotically flat, everywhere non-singular configura…
Kerr black holes with synchronised scalar hair and boson stars in the Einstein-Friedberg-Lee-Sirlin model
J Kunz, I Perapechka, Ya Shnir
We study a new family of self-gravitating axially-symmetric, rotating boson stars in the two-component Friedberg-Lee-Sirlin model minimally coupled to Einstein gravity in four spac…
Kerr black holes with parity-odd scalar hair
J. Kunz, I. Perapechka, Ya. Shnir
We study Kerr black holes with synchronised non-trivial parity-odd massive scalar hair in four dimensional asymptotically flat space-time. These axially symmetric stationary spinni…
Gravitating solitons and black holes with synchronised hair in the four dimensional O(3) sigma-model
C. Herdeiro, I. Perapechka, E. Radu +1
We consider the non-linear sigma-model, composed of three real scalar fields with a standard kinetic term and with a symmetry breaking potential in four spacetime d…
