What do the letters at the bottom axis of the hr diagram represent?
The letters at the bottom axis of the Hertzsprung-Russell (HR) diagram represent the spectral classes of stars, ranging from hotter (O, B) to cooler (G, K, M). Each letter corresponds to a different temperature of the star.
What does the hr diagram compare?
The HR diagram compares the luminosity (brightness) of stars against their surface temperature or spectral type. This plot helps astronomers classify stars based on their intrinsic characteristics and evolutionary stages.
What is the HR diagram based on?
The Hertzsprung-Russell (HR) diagram is based on plotting a star's luminosity against its temperature or spectral type. This diagram helps astronomers classify stars based on their evolutionary stage and enables them to study relationships between a star's properties such as temperature, luminosity, and size.
What two star characteristics does Hertzsprung Russell diagram compare?
The HR Diagram compares the relationship between the stars' absolute magnitudes or luminosities versus their spectral types or classifications and effective temperatures.
What diagram graphs types of stars?
I believe you are thinking of a Hertzsprung-Russell diagram, but this denotes the relationship between a stars luminosity and it's spectral class.It has nothing to do with the life cycle of a star.See related questions for more information

Where is the Sirius star on h-r diagram?
Sirius is a binary star. Sirius A has a spectral type of A1V and will appear on the HR in the top left corner. Sirius B has a spectral type of DA2 and will appear on the HR in the bottom left corner as a white dwarf.
What is the HR diagram based on?
The Hertzsprung-Russell (HR) diagram is based on plotting a star's luminosity against its temperature or spectral type. This diagram helps astronomers classify stars based on their evolutionary stage and enables them to study relationships between a star's properties such as temperature, luminosity, and size.
When a star changes its position in the HR diagram it is because the star is?
evolving into a later stage. For example, a G2 star going into a red giant (M type)
What two star characteristics does the hertzsprung - Russell diagram compare?
The HR Diagram compares the relationship between the stars' absolute magnitudes or luminosities versus their spectral types or classifications and effective temperatures.
What two star characteristics does Hertzsprung Russell diagram compare?
The HR Diagram compares the relationship between the stars' absolute magnitudes or luminosities versus their spectral types or classifications and effective temperatures.
What does the HR diagram depict?
The HR diagram, also known as the Hertzsprung-Russell diagram, depicts the relationship between the luminosity and temperature of stars. It shows how stars are distributed in terms of their brightness and temperature, allowing astronomers to classify stars based on these characteristics.
How do you read a HR diagram?
scatter graph of stars showing the relationship between the stars' absolute magnitudes orluminosities versus their spectral types orclassifications and effective temperatures.
Does An HR diagram plots a stars luminosity and surface temperature?
Yes, an HR diagram plots a star's luminosity (brightness) against its surface temperature, also known as color or spectral type. This graph shows the relationship between these two characteristics for different stars, allowing astronomers to classify and study them.
Why is there no neurton stars in the hr diagram?
Of course they are on the HR diagram. They are simply not on the main sequence.
Where are stars on the hr diagram?
The HR diagram contains only stars - so everywhere.
