Neutron stars with primary scalar hair
Hamza Boumaza, Christos Charmousis, David Langlois +1
We investigate static and spherically symmetric neutron star solutions endowed with primary scalar hair in a subfamily of Degenerate-Higher-Order-Scalar-Tensor (DHOST) theories of…
Radial Perturbations of Black Holes in DHOST Theories
Christos Charmousis, Simon Iteanu, David Langlois +1
We study radial perturbations of static black holes with primary hair in a subfamily of degenerate higher-order scalar-tensor (DHOST) theories. We recast the equation of motion for…
Slowly rotating Black Holes in DHOST Theories
Hugo Candan, Karim Noui, David Langlois
We study slowly rotating black hole solutions within Degenerate Higher Order Scalar Tensor (DHOST) theories. Starting from a static, spherically symmetric metric solution of a DHOS…
Axial perturbations of black holes with primary scalar hair
Christos Charmousis, Simon Iteanu, David Langlois +1
We study axial perturbations of static black holes with primary hair in a family of degenerate higher-order scalar-tensor (DHOST) theories. These solutions possess a scalar charge,…
Degenerate Higher-Order Maxwell Theories in Flat Space-Time
Aimeric Colléaux, David Langlois, Karim Noui
We consider, in Minkowski spacetime, higher-order Maxwell Lagrangians with terms quadratic in the derivatives of the field strength tensor, and study their degrees of freedom. Usin…
Numerical computation of quasinormal modes in the first-order approach to black hole perturbations in modified gravity
Hugo Roussille, David Langlois, Karim Noui
We present a novel approach to the numerical computation of quasi-normal modes, based on the first-order (in radial derivative) formulation of the equations of motion and using a m…
Classification of generalised higher-order Einstein-Maxwell Lagrangians
Aimeric Colléaux, David Langlois, Karim Noui
We classify all higher-order generalised Einstein-Maxwell Lagrangians that include terms linear in the curvature tensor and quadratic in the derivatives of the electromagnetic fiel…
Cosmological evolution in DHOST theories
Marco Crisostomi, Kazuya Koyama, David Langlois +2
In the context of Degenerate Higher-Order Scalar-Tensor (DHOST) theories, we study cosmological solutions and their stability properties. In particular, we explicitly illustrate th…
