Formation of scalar hair on Gauss-Bonnet solitons and black holes
Yves Brihaye, Betti Hartmann, Sardor Tojiev
We discuss the formation of scalar hair on Gauss-Bonnet solitons and black holes in 5-dimensional Anti-de Sitter (AdS) space-time. We present new results on the static case and poi…
Compact Boson Stars
Betti Hartmann, Burkhard Kleihaus, Jutta Kunz +1
We consider compact boson stars that arise for a V-shaped scalar field potential. They represent a one parameter family of solutions of the scaled Einstein-signum-Gordon equations.…
Hairy charged Gauss-Bonnet solitons and black holes
Yves Brihaye, Betti Hartmann
We study the stability of (4+1)-dimensional charged Gauss-Bonnet black holes and solitons. We observe an instability related to the condensation of a scalar field and construct exp…
