Black Hole Criticality in the Brans-Dicke Model
Steven L. Liebling, Matthew W. Choptuik
Abstract
We study the collapse of a free scalar field in the Brans-Dicke model of gravity. At the critical point of black hole formation, the model admits two distinctive solutions dependent on the value of the coupling parameter. We find one solution to be discretely self-similar and the other to exhibit continuous self-similarity.
