HF electric properties of the astrophysical plasmas

Abstract

The HF characteristics of astrophysical plasmas was determined on the basis of numerically calculated values for the dense plasma conductivity in an external HF electric field. The examined range of plasma frequencies covers the IR, visible and UV regions and considers electronic number density and temperature important for different stellar models. The results presented here are important for the investigation of atmosphere plasmas of astrophysical objects, for example, white dwarfs with different atmospheric compositions (DA, DC etc.), and for the investigation of some other stars (M-type red dwarfs, Sun etc.) as well as for laboratory plasma research.
