The optical properties of very cold star plasmas with low densities are analyzed by the use of Fermi-Dirac statistics. For the present collisional plasma the frequency of electron-ion collision is very large relative to the optical and infra-red frequencies. A quantum mechanical equation for the frequency of collisions is developed by the use of Fermi-Dirac statistics which includes screening effects. The stability of stellar cold plasma is described, including the relation between the radius of stars and their densities. For ultra-cold, low density star plasma the star radius is larger than that of white dwarfs and the plasma is transparent. Many such stars may extend over space with large gravitational forces. These results may have implication to dark matter.
