Les relations de Milne-Barbier-Unsöld ? [SSA]

http://arxiv.org/abs/1711.07026


This short review aims at clarifying upon the origins of the well-known Eddington-Barbier relationships. The later relate indeed both the emergent specific intensity and the flux to the stellar photospheric source function at certain specific optical depths. Hereafter we shall discuss about the very assumptions used for the original derivation of Barbier (1943). We also point to the fact that Milne (1921) had already formulated these two relations.
