As Gustav Kirchhoff understood [1], Fraunhofer lines are produced when light is absorbed by gaseous atoms located above the level of the solar surface where the continuous photospheric spectrum is emitted.
Another story concerns Kirchhoff's investigation of whether the Fraunhofer lines could reveal the presence of gold in the sun.
Thus, Fraunhofer's dark D line reveals the presence of sodium in the Sun, while the rest of the Fraunhofer lines indicate the presence of different chemical elements, including the Sun's major constituent, hydrogen.
