comment Appearance (popularity) ranking of stars?
@AB:Intuition suggests larger, more complicated things are more rare, but physics governing different sections of the figure varies -manifested in the variations in slope. The authors of the figure, Binggeli and Hascher speculate a few underlying processes, but point out, "that our primary goal is not to find a sort of cosmological principle that governs the mass distribution function of the universe, but to provide a valuable piece of cosmography. A good knowledge of the frequency distribution of things in the universe is an end in itself." Which addresses the original question.
