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…
