Inverse bremsstrahlung in dwarf atmospheres: the absorption coecients and Gaunt factors
Abstract
In this work we determine the electron-ion inverse bremsstrahlung characteristics for the case of the white dwarf atmospheres where such plasma characteristics as plasma density and temperature change in wide region. It is presented that determination of these characteristics, i.e. the absorption coefficients and Gaunt factors can be successfully performed within the whole range of electron densities and temperatures which is relevant for the corresponding atmospheres. The results are obtained for the DB white dwarf models in the wavelength region 100 nm < λ < 3000 nm. These results can be of interest and use in investigation of different stellar and laboratory plasmas.
