Web23 aug. 2024 · Several decades of observations of the most massive and most luminous stars have revealed a complex upper HR Diagram, shaped by mass loss, and inhabited by a variety of evolved stars exhibiting the consequences of their mass loss histories. This introductory review presents a brief historical overview of the HR Diagram for massive … Weband colder stars to the right. More luminous (intrinsically bright) stars lie at the top of the diagram and lower luminosity (intrinsically faint) stars lie at the bottom of the diagram. Review that stars are grouped into four different categories in the HR Diagram: Main Sequence Stars: The characteristic of all these stars are that they are all reflections images

The H-R diagram can be used by scientists to roughly measure how far away a star cluster or galaxy is from Earth. This can be done by comparing the apparent magnitudes of the stars in the cluster to the absolute magnitudes of stars with known distances (or of model stars).
