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…
