Context triple: [Hertzsprung–Russell diagram, relatedTo, Morgan–Keenan classification]
  • A. Harvard spectral classification of stars chosen
    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.
  • B. Hubble sequence
    The Hubble sequence is a morphological classification scheme that organizes galaxies into categories such as ellipticals, spirals, and irregulars based on their visual appearance.
  • C. Hertzsprung–Russell diagram
    The Hertzsprung–Russell diagram is a fundamental astronomical chart that plots stars’ luminosities against their temperatures or spectral types, revealing key patterns of stellar evolution and classification.
  • D. Cepheid
    Cepheid is a molecular diagnostics company known for its rapid, automated PCR-based testing systems used in clinical and research settings.
  • E. Henry Draper Catalogue
    The Henry Draper Catalogue is a pioneering astronomical star catalog that provides spectral classifications and designations for hundreds of thousands of stars, forming a foundational resource in stellar astronomy.
  • F. None of above.
  • G. Unsure - the case is ambiguous/there is not enough information to decide.
