Low frequency twisted waves in a self-gravitating nonextensive complex plasma

Abstract The effects of dust-dust self-gravitational force and nonextensive characteristics plasma species on the low frequency twisted waves owing to helical wave structure in complex (dusty) plasmas are analyzed. electrons ions modelled by q-distribution function while massive dust particles Maxwellian distributed. incorporated Vlasov equation kinetic theory where perturbed distribution function, electrostatic gravitational potentials expressed with Laguerre-Gauss functions. governing equations solved together under paraxial approximations. dispersion relations damping rates dust-acoustic (TDAWs) obatined for two situations; a) super-extensivity (q<1) b) sub-extensivity (q>1). self-gravity, nonextensivity twist parameter significantly modified basic features waves. This study contributes our understanding dynamics interstellar clouds, considering interplay nonextensivity, phase structures. obtained theoretical numerical results provide valuable insights into behavior these offer a foundation further investigations this field. However, topic can be enhanced through combination models, simulations observational data.
