TOOLS IN ASTRONOMY SPECTROSCOPY
... 1. Know that starlight is often broken up into component wavelengths with diffraction gratings to produce stellar spectra. 2. Understand how stellar spectra are classified as A, B, C, D, E and so on, based on prominent characteristics. 3. Understand how stellar spectra are related to composition and ...

Seasons and the Appearance of the Sky
