  The free electron model with Boltzmann statistics for spherical low-density
plasmas (Scientific Reports 9. 20384, 2019) is developed further by numerical
calculations with asymptotic relations obtaining the density of electrons, mass
densities and the potentials of such plasmas. Solutions are developed as
function of a pure number x proportional to the distance from the stellar
plasma center (galaxy center) with extremely small coefficient so that these
solutions are essentially functions of large astronomical distances and masses.
The present plasma is divided into a central part and very long tail where most
of the large mass of this plasma is included in the long stellar plasma tail.
The present model is specialized to completely ionized Hydrogen plasma where
emission and absorption of spectral lines can be neglected in the low density
stellar plasma. It is shown that the present low-density plasma might represent
dark halo which permeates and surrounds the compact galactic stars. Such plasma
is found to be transparent in most of the EM spectrum.
