Model spectrum

A model spectrum is an artificial spectrum of a star made by recreating the absorption or emission features seen in the spectrum. A model spectrum will usually be of a specific spectral type of star. It may include other properties of the star, such as a surrounding nebula, presence or lack of an extended atmosphere, or a circumstellar dust disc.
