( Rubab Manzoor (Mathematics /SSC), JCR LISTED (IF:4:912))https://escholar.umt.edu.pk/handle/123456789/3220This 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.enMathematicsScalar Field Filamentary Structure Radial Oscillation Polytropic Index Finite RadiusArticle
