Abstract

This chapter focuses on the fundamental origin of lines observed in astrophysical spectra. Some properties of the atomic world are qualitatively explained as an introduction to spectroscopy. General laws and rules are exposed and applied to celestial bodies. Please note: it is possible to read this chapter quickly concentrating only on the sentences in bold type.
