Cold scalar-tensor black holes coupled to a massless scalar field
arXiv:gr-qc/0305053
Abstract
New four-dimensional black hole solutions of Brans-Dicke equations with a negative constant , coupled to a massless scalar field, are presented. The temperature of these black holes is zero and the horizon area is infinite. An astrophysical application is also discussed.
