Lecture 31: The Properties of Stars

What are the observed properties of stars? This lecture is a quick review of the basic observational properties of stars, introducing luminosity, spectral classification, the luminosity-radius-temperature relation, and the Hertzsprung-Russell (H-R) diagram. This sets up the empirical basis of subsequent lectures on the lives and deaths of stars. Recorded live on 2009 Nov 9 in Room 1005 Smith Laboratory on the Columbus campus of The Ohio State University.
