  • A. 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.
  • B. 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.
  • 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. Fundamental catalogue of stars
    Fundamental Catalogue of Stars is a major 19th-century astronomical star catalog compiled under the direction of Arthur Auwers, providing highly accurate positions and motions for thousands of stars.
  • E. Recherches sur le spectre solaire
    Recherches sur le spectre solaire is a foundational 19th-century scientific work by Anders Jonas Ångström that systematically analyzed the solar spectrum and advanced the study of spectroscopy.
  • F. None of above. chosen
  • G. Unsure - the case is ambiguous/there is not enough information to decide.
