Nonlinear instability and scalar clouds of spherical exotic compact objects in scalar-Gauss-Bonnet theory
Abstract In this work, we present a new type of scalar clouds supported by spherically symmetric horizonless compact objects in the scalar-Gauss–Bonnet theory. Unlike the previous spontaneous scalarization that is triggered by the tachyonic instability, our scalarization arises from a nonlinear inst...
