Abstract
This paper is devoted to the study of the cylindrically
symmetric stellar filaments in self-interacting Brans–
Dicke gravity. For this purpose, we construct polytropic filamentary
models through a generalized Lane–Emden equation
in the Newtonian regime. The resulting models depend
upon the values of the cosmological constant (due to the
scalar field) along with the polytropic index and represent a
generalization of the corresponding models in general relativity.
We also investigate the fragmentation of the filaments by
exploring the radial oscillations through a stability analysis.
This stability criterion depends only upon the adiabatic index.
