174-177In the present paper, a linear relationship in stellar optical spectra has been found by using a spectroscopical method used on optical light sources where it is possible to organize atomic data in a linear structure. This method is based on a new intensity formula in optical emission spectroscopy (OES). Like the HR-diagram, it seems possible to organize the luminosity of stars from different spectral classes. It is also possible to determine the mean electron temperature of the optical layers (photospheres) of the stars as it is for atoms in the laboratory plasmas. The mean value of the ionization energies of the different elements of the stars has shown to be very significant for each star. The hydrogen Balmer absorption ...
