-
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.
Harvard Revised Photometry
Harvard Revised Photometry is a comprehensive star catalog produced by the Harvard College Observatory that provided standardized photometric measurements for thousands of stars and became a foundational reference in stellar astronomy.
-
C.
Hubble sequence of galaxy classification
The Hubble sequence of galaxy classification is a morphological system that organizes galaxies into categories such as ellipticals, spirals, and irregulars based on their visual appearance.
-
D.
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.
-
E.
Eddington standard model of stars
The Eddington standard model of stars is a theoretical framework in stellar astrophysics that describes the internal structure and energy transport of stars under simplifying assumptions of radiative equilibrium and constant opacity.
- F. None of above.
- G. Unsure - the case is ambiguous/there is not enough information to decide.
