Classification. As discussed in the text, Annie Jump Cannon and her colleagues developed our modern system of stellar classification. Why do you think rapid advances in our understanding of stars followed so quickly on the heels of their efforts? What other areas in science have had huge advances in understanding following directly from improved systems of classification?

Stellar classification Stellar Spectra
SOLVED:Use the information in Example 1.5 from "The Classification of Stellar Spectra" to calculate the ratio of doubly to singly ionized calcium atoms (Ca III/Ca II) in the Sun's photosphere. The ionization energy of Ca II is χII=11.9 eV . Use ZIII=1 for the partition function of Ca III. Is your result consistent with the statement in Example 1.5 that in the solar photosphere, "nearly all of the calcium atoms are available for forming the H and K lines of calcium"?
