Abstract: Spontaneous scalarization is a scenario in some scalar-tensor theories of gravity where non-perturbative (order-of-unity strength) scalar fields can develop near neutron stars. I will explain the basics of spontaneous scalarization for massive fields, and how we can use observations to constrain the parameter space of these theories, both in single neutron stars and dynamical mergers.
