The Screening Characteristics of the Dense Astrophysical Plasmas: The Three-Component Systems

Abstract

Abstract:As the object of investigation, astrophysical fully ionized electron-ion plasma is chosen with positively charged ions of two different kinds, including the plasmas of higher non-ideality. The direct aim of this work is to develop, within the problem of finding the mean potential energy of the charged particle for such plasma, a new model, self-consistent method of describing the electrostatic screening. Within the presented method, such extremely significant phenomena as the electron-ion and ion-ion correlations are included in the used model. We wish to draw attention to the fact that the developed method is suitable for astrophysical applications. Here we keep in mind that in outer shells of stars, the physical conditions change from those that correspond to the rare, practically ideal plasma, to those that correspond to extremely dense non-ideal plasma.

The development of simplified approach in describing of the ionic field to emitter interaction in stellar and laboratory plasmas

“…The usage of Cut-off Coulomb model potential was applied in the fully quantum mechanical solution for determining the optical properties of dense hydrogen plasma. Up until now the results were presented and used for instance see Dimitrijević et al (2018); Srećković et al (2018); Mihajlov et al (2015Mihajlov et al ( , 2011; Ignjatović et al (2017); Ignjatović et al (2009). Both Coulomb as well as cut-off Coulomb potential is presented in Eq.…”

The Application of the Cut-Off Coulomb Model Potential for the Calculation of Bound-Bound State Transitions

“…By now, this approximation has been used in order to describe transport properties of dense plasmas (e.g., [1,5,6]), but it was clear that it could be applied to some absorption processes in non-ideal plasmas too [3,[7][8][9]. This topic itself, and the search for more consistent models of screening and more realistic potentials in plasmas is still continuing and is very real (e.g., [10][11][12][13] and references therein).…”
