The Hertzsprung-Russell diagram (H-R diagram) is a graph of stars showing the stars' luminosities or absolute magnitude versus their spectral type which is related to their effective temperature.

Identify two ways in which astronomers can use an H-R diagram?
Classify stars and to understand how stars change over time
What is the H R diagram?
The H-R diagram is a graphical tool used to classify stars according to color, temperature, spectral type, luminosity, and evolutionary stage. H-R stands for Hertzsprung-Russell.
What is h r diagram?
The H-R diagram is a graphical tool used to classify stars according to color, temperature, spectral type, luminosity, and evolutionary stage. H-R stands for Hertzsprung-Russell.
How do you classify stars by age?
you dont. sciensists never use age to classify a star
What is the brightest star on the H-R diagram?
The "supergiant" stars are the brightest stars on the H-R diagram.

How does the hertzsprung Russell diagram classify stars?
increase in absolute brightness as they increase in temperature.Increase in brightness as they increase in temperature
What does a H R Diagram compare?
The H-R diagram compares a star's surface temperature to its absolute brightness.
when was the H and R diagram created and how?
The Hertzsprung-Russell diagram, or H-R diagram, was created in 1911 by Ejnar Hertzsprung and Henry Norris Russell. They plotted the luminosity of stars against their surface temperature to classify and study stellar populations. This diagram revolutionized our understanding of stars and their life cycles.
Who classifies stars?
Astronomers classify stars.
What is the H R diagram?
The H-R diagram is a graphical tool used to classify stars according to color, temperature, spectral type, luminosity, and evolutionary stage. H-R stands for Hertzsprung-Russell.
What is h r diagram?
The H-R diagram is a graphical tool used to classify stars according to color, temperature, spectral type, luminosity, and evolutionary stage. H-R stands for Hertzsprung-Russell.
Interpret an H-R diagram?
An H-R Diagram (Hertzsprung and Russell) is used to classify stars based on their size and brightness. The main sequence stars, such as our sun, are the medium stars, and take up the middle f the diagram, while the giants and dwarves are located on either side. http://www.eso.org/public/outreach/eduoff/cas/cas2002/cas-projects/bulgaria_comaber_1/hr_local.gif <- shows what an H-R diagram looks like.
How do you classify stars by age?
you dont. sciensists never use age to classify a star
Where are stars on the hr diagram?
The HR diagram contains only stars - so everywhere.
What is the purpose of the H-R diagram?
That is short for Hertzsprung-Russell diagram. It is a diagram in which the brightness of stars is plotted against their surface temperature (which can be deduced from their color). It turns out that most stars (basically, the ones that get their energy from fusion of hydrogen to helium) are on, or close to, one particular curve in the diagram - the so-called "main sequence".
What are characteristics used to classify a star?
you classify stars by color, temperature, size, composition, and brightness.
