Description

This talk will present exact solutions of non-rotating black holes and neutron stars, with primary scalar hair, obtained in a subfamily of Degenerate Higher-Order Scalar-Tensor (DHOST) theories, which include and extend Horndeski theories. I will also discuss the perturbations of these black hole solutions.
