The day that my students create and interpret the Hertzsprung-Russell Diagram is one of my absolute favorite days of the year. The Hertzsprung-Russell Diagram is in the zone of proximal H-R Diagram. Hertzsprung-Russell Diagram. The Hertzsprung-Russell Diagram is a graphical tool that astronomersuse to classify stars according to their luminosity, spectral type,color, temperature and evolutionary stage. Stars in the stable phase of hydrogen burningliealong the Main Sequence according to their mass. Hertzsprungův-Russellův diagram vyjadřuje závislost povrchové teploty hvězd na jejích svítivosti nebo absolutní magnitudě v různých fázích vývoje.

luminosity. Think of "luminosity" as a way to define the brightness of an object. THE HR DIAGRAM THE MOST FAMOUS DIAGRAM in ASTRONOMY Mike Luciuk 1.INTRODUCTION Late in the nineteenth century, astronomers had tools that revealed a great deal about stars. By that time, advances in telescope design and photographic emulsions were becoming mature. The Hertzsprung-Russell diagram (or HR diagram) is constructed in logarithmic coordinates.
