The Hertzsprung-Russell diagram graphs stars' brightness and corresponding temperatures in addition to their classifications. The stars' colors are due to their temperatures.

Do stars have the same brightness and sizes?
No. Stars vary greatly in size and brightness.
Which main-sequence stars are brightest?
The most massive main sequence stars are the brightest, (O main sequence star on Hertzsprung-Russel Diagram). Main sequence stars obey a mass-luminosity relation. On the H-R diagram the vertical axis is the brightness. So the stars along the top are the brightest (intrinsically).
What is a stars brightness known as?
A star's brightness is known as its magnitude. Stars with lower magnitude numbers are brighter than stars with a higher magnitude number.
Are main sequence stars hotter or cooler than the sun?
They are both hotter and cooler because the main sequence contains a lot of stars including the Sun. The main sequence is a region on a Hertzsprung-Russell diagram which plots stars on a graph of brightness against surface temperature. Each star is a point on the diagram because it has one value of brightness and one of temperature. All the main-sequence stars lie on or near a line drawn from top left to lower right. The Sun is about halfway along the main sequence.
What does an h-r diagram relate a stars temperature to?
The temperature is displayed along the horizontal axis while the vertical axis is the star's absolute magnitude. So the HR diagram is a scatter diagram relating temperature and brightness, and eah star occupies one point.
The hr diagram graphs what 2 things?
The temperature and luminosity of stars.
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 the HR diagram do?
It shows certain key characteristics (brightness, and temperature) of stars.
What does a H R Diagram compare?
The H-R diagram compares a star's surface temperature to its absolute brightness.
What does the Hertzsprung-Russell diagram show about main-sequence stars?
increase in absolute brightness as they increase in temperature.Increase in brightness as they increase in temperature
What is the hertzspung-rissell diagram?
The H-R diagram is used to determine the color (brightness) and temperature of the stars, a simple chart with picture of stars with different siize, color, and temperature
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
What two caracteristics of a star are plotted on the Hertzsprung Russell diagram?
Brightness and Temperature are the two characteristics plotted on the H-R diagram a diagram used to plot the absolute magnitude of stars and their temperatures

Do stars have the same brightness and sizes?
No. Stars vary greatly in size and brightness.
What is a b-r diagram?
A Hertzsprung-Russell (H-R) diagram, also known as a color-magnitude diagram, is a graph that plots stars based on their absolute magnitude (brightness) and spectral type (color). It is a valuable tool for studying the properties and evolutionary stage of stars within a specific population.
Which main-sequence stars are brightest?
The most massive main sequence stars are the brightest, (O main sequence star on Hertzsprung-Russel Diagram). Main sequence stars obey a mass-luminosity relation. On the H-R diagram the vertical axis is the brightness. So the stars along the top are the brightest (intrinsically).
