Stellar Structure in a Newtonian Theory with Variable G

A Newtonian-like theory inspired by the Brans–Dicke gravitational Lagrangian has been recently proposed us. For static configurations, coupling acquires an intrinsic spatial dependence within matter distribution. Therefore, interior of astrophysical configurations may provide a testable environment for this approach as long no screening mechanism is evoked. In work, we focus on stellar hydrostatic equilibrium structure in such varying Newtonian G scenario. modified Lane–Emden equation presented and its solutions various values polytropic index are discussed. The role played parameter ω, analogue parameter, physical properties stars
