Analyzing Starlight

A self-checking practice quiz on analyzing starlight: what starlight tells us, star colors and temperature, spectral classification (OBAFGKM), composition from spectra, the Doppler effect and stellar motion, brightness and magnitude, and measuring stellar properties. Every question is multiple choice and shown one at a time, and the set is drawn fresh each time you take it. At the end you receive a report showing how many you answered correctly.
