-
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.
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.
-
C.
Hertzsprung
Hertzsprung is a surname most notably associated with Danish astronomer Ejnar Hertzsprung, co-creator of the Hertzsprung–Russell diagram fundamental to stellar astrophysics.
-
D.
Yerkes galaxy classification
Yerkes galaxy classification is a detailed system for categorizing galaxies based on their spectral and photometric properties, expanding on earlier morphological schemes to incorporate stellar population and luminosity characteristics.
-
E.
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.
- F. None of above.
- G. Unsure - the case is ambiguous/there is not enough information to decide.
