Non-linear stability of soliton solutions for massive tensor-multi-scalar-theories
Riccardo Falcone, Daniela D. Doneva, Kostas D. Kokkotas +1
The aim of this paper is to study the stability of soliton-like static solutions via non-linear simulations in the context of a special class of massive tensor-multi-scalar-theorie…
Constraining the equation of state in modified gravity via universal relations
Victor I. Danchev, Daniela D. Doneva
Modern multi-messenger astronomical observations and heavy ion experiments provide new insights into the structure of compact objects. Nevertheless, much ambiguity remains when it…
Spin-induced scalarization of Kerr black holes with a massive scalar field
Daniela D. Doneva, Lucas G. Collodel, Christian J. Krüger +1
In the present paper we study the onset of the spin-induced scalarization of a Kerr black hole in scalar-Gauss-Bonnet gravity with a massive scalar field. Our approach is based on…
Black hole scalarization induced by the spin -- 2+1 time evolution
Daniela D. Doneva, Lucas G. Collodel, Christian J. Krüger +1
The scalarization is a very interesting phenomena allowing to endow a compact object with scalar hair while leaving all the predictions in the weak field limit unaltered. In Gauss-…
No-hair theorems for non-canonical self-gravitating static multiple scalar fields
Daniela Doneva, Stoytcho Yazadjiev
We prove under certain assumptions no-hair theorems for non-canonical self-gravitating static multiple scalar fields in spherically symmetric spacetimes. It is shown that the only…
Rotating tensor-multiscalar black holes with two scalars
Lucas G. Collodel, Daniela D. Doneva, Stoytcho S. Yazadjiev
We construct hairy black hole solutions in a particular set of tensor-multi-scalar theories of gravity for which the target-space admits a Killing vector field with periodic flow t…
