INVESTIGATION OF THE DAMPING CONSTANT OF FRAUNHOFER'S LINES IN SOLAR ATMOSPHERE
Odessa Astronomical Publications, 2017 To define chemical contents of elements in stars' atmospheres we need reliable data on their damping in spectral lines. We have found distinct expressions for damping constant with consideration of several mechanisms that in the expansion of spectral ...
