TL;DR
This paper investigates static spheroidal solutions in Jordan-Brans-Dicke theory, highlighting how scalar fields influence the shape and properties of self-gravitating objects, resulting in nonflat solutions unlike in general relativity.
Contribution
It introduces new static spheroidal solutions in JBD theory considering scalar field anisotropic stresses, expanding understanding of self-gravitating objects in alternative gravity theories.
Findings
Scalar fields significantly affect the structure of self-gravitating objects.
JBD theory admits nonflat static spheroidal solutions, unlike general relativity.
Scalar stresses influence the shape and properties of these objects.
Abstract
The static spheroidal solutions of Jordan-Brands-Dicke theory (JBD) are studied. We consider the effect of the anisotropic stresses of scalar field on the shape of JBD self-graviting objects. It is shown that scalar fields can have significant effect on the structure and properties of self-graviting objects. In contrast with general relativity in JBD theory there are nonflat static spheroidal solutions.
