Spherical Self-Similar Solutions in Einstein-Multi-Scalar Gravity
نویسندگان
چکیده
We consider a general non-linear sigma model coupled to Einstein gravity and show that in spherical symmetry and for a simple realization of self-similarity, the spacetime can be completely determined. We also examine some more specific matter models and discuss their relation to critical collapse. ∗Electronic Address: [email protected] †On leave from Departamento de F́ısica Teórica, Universidade do Estado do Rio de Janeiro, Cep. 20550-013, Rio de Janeiro – RJ, Brazil.

دستهای از جوابهای دقیق گرانش با مشتقات بالاتر در چهار بعد
In this paper we consider the action of higher derivative gravity up to the second order terms in the scalars made from the Ricci scalar, Ricci and Riemann tensors. We use the Bach- Lanczos identity of the Weyl tensor in four dimensions and show that the solutions of 4-dimensional Einstein equations with cosmological constant term in vacuum, which are known as Einstein metrics, satisfy the fie...
متن کاملA Numerical Study of Boson Stars: Einstein Equations with a Matter Source
The study of the properties and dynamics of self-gravitating bosonic objects in Einstein gravity was conducted. Bosons are promising candidates for dark matter. They can form compact objects through a Jeans instability mechanism. We studied boson stars made up of self-gravitating scalar fields, with and without nonlinear self-couplings. These are non-topological solutions of the coupled Einstei...
متن کاملSpherical Structures in Conformal Gravity and its Scalar-Tensor Extension
We study spherically-symmetric structures in Conformal Gravity and in a scalar-tensor extension and gain some more insight about these gravitational theories. In both cases we analyze solutions in two systems: perfect fluid solutions and boson stars of a self-interacting complex scalar field. In the purely tensorial (original) theory we find in a certain domain of parameter space finite mass so...
متن کاملExact static solutions in four dimensional Einstein-Maxwell-Dilaton gravity
Classes of exact static solutions in four-dimensional Einstein-MaxwellDilaton gravity are found. Besides of the well-known solutions previously found in the literature, new solutions are presented.It’s shown that spherically symmetric solutions, except the case of charged dilaton black hole, represent globally naked strong curvature singularities. The scalar field is believed to play an importa...

Pauli (or Einstein) frame is used to study the Brans-Dicke gravity theory, minimally coupled with dilatonic Brans-Dicke scalar field, whose solutions involve degenerate metrics. Some of these solutions exhibit transitions from an Euclidean domain to a Lorentzian space-time corresponding to a spatially flat Robertson-Walker cosmology.
