Deriving chemical composition from spectra

So, for example, if a hydrogen atom happens to be in the n=2 excited state, and a photon of energy E = 2.55 eV and wavelength 486 nm passes by, then the atom will absorb the photon and hop up into the n=4 state. This transition will remove photons of wavelength 486 nm from the star''s spectrum; we will see an absorption line at this wavelength ...

Phase-Composition Diagram -

Phase-Composition Diagram. A plot of temperature versus composition of a solid solution mineral. Unlike a phase diagram, there is a region where the material will exist in a partially solid and a partially liquid phase. The line dividing this region and the solid is known as the solidus line; that separating the liquid region is the liquidus line .
