  • A. On the Relations between the Spectra and Other Characteristics of the Stars
    "On the Relations between the Spectra and Other Characteristics of the Stars" is a landmark 1914 paper by Henry Norris Russell that helped establish the relationship between stellar spectral type, luminosity, and other properties, laying groundwork for the Hertzsprung–Russell diagram and modern stellar astrophysics.
  • B. A Catalogue of 838 Principal Fixed Stars
    A Catalogue of 838 Principal Fixed Stars is an influential 19th-century astronomical star catalog compiled by Francis Baily that systematically lists and refines the positions of key stars for observational and navigational use.
  • C. Harvard spectral classification of stars
    The Harvard spectral classification of stars is an early 20th-century system that categorizes stars by their spectral characteristics and surface temperatures into types O, B, A, F, G, K, and M, forming the basis of modern stellar classification.
  • D. Secchi classes of stellar spectra
    Secchi classes of stellar spectra are an early system of classifying stars based on the patterns in their light spectra, developed by astronomer Pietro Secchi and foundational to modern stellar classification.
  • E. Armagh Catalogue of Stars
    The Armagh Catalogue of Stars is a 19th-century astronomical star catalog compiled at Armagh Observatory, listing precise positions and related data for thousands of stars.
