A.
de Vaucouleurs system of galaxy classification
The de Vaucouleurs system of galaxy classification is an extended and more detailed refinement of the Hubble scheme that categorizes galaxies using a three-dimensional notation incorporating features such as bars, rings, and spiral arm structure.
-
B.
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.
-
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.
