Black holes with primary scalar hair
Athanasios Bakopoulos, Christos Charmousis, Panagiota Kanti +2
We present explicit black holes endowed with primary scalar hair within the shift-symmetric subclass of Beyond Horndeski theories. These solutions depend, in addition to the conven…
Exact black hole solutions in higher-order scalar-tensor theories
Eugeny Babichev, Christos Charmousis, Nicolas Lecoeur
In this chapter, we discuss explicit black hole solutions in higher-order scalar-tensor theories. After a brief recap of no-hair theorems, we start our discussion by so-called stea…
Rotating black holes embedded in a cosmological background for scalar-tensor theories
Eugeny Babichev, Christos Charmousis, Nicolas Lecoeur
We present solutions of DHOST theories describing a rotating black hole embedded in an expanding universe. The solution is constructed by conformal transformation of a stealth Kerr…
Selecting Horndeski theories without apparent symmetries and their black hole solutions
Eugeny Babichev, Christos Charmousis, Mokhtar Hassaine +1
Starting from a generalised Kaluza-Klein action including arbitrary Horndeski potentials, we establish integrability and compatibility conditions that solve the generic field equat…
Conformally coupled scalar in Lovelock theory
Eugeny Babichev, Christos Charmousis, Mokhtar Hassaine +1
In arbitrary higher dimension, we consider the combination of Lovelock gravity alongside a scalar-tensor action built out of higher order operators and Euler densities. The latter…
