An H-R diagram for a group of stars cannot be produced by plotting their
A)Luminosities versus masses
B)Magnitudes versus spectral types
C)Temperatures versus luminosities
D)Colors versus magnitudes

Question

Quizplus · Accepted Answer

An H-R (Hertzsprung-Russell) diagram plots the luminosities (or absolute magnitudes) of stars against their temperatures (or spectral types), not their masses. Choices B, C, and D are all valid ways to represent data on an H-R diagram, reflecting the relationship between a star's brightness, temperature, color, and spectral type.
