The HR diagram has the star's temperature along the horizontal axis and the absolute magnitude (brightness) along the vertical axis. Each star is represented by a single dot.
Higher temperature is usually associated with more brightness so many stars lie on or near a line on the diagram called the Main Sequence. Red giant stars are found on the upper right hand quarter because they are relatively cool but still very bright.

Which part of the main sequence in the HR diagram contains the stars that took the longest to reach the main sequence?
The HR diagram does not reference stars on their way to the main sequence, only during or after.
What type of relationship is shown on a HR diagram?
It is a chart showing a scatter chart of stars according to their temperature and their luminosity (or absolute magnitude).
The hr diagram graphs what 2 things?
The temperature and luminosity of stars.
What does the HR diagram do?
It shows certain key characteristics (brightness, and temperature) of stars.
Why is the hr diagram useful in plotting the life cycles of stars?
I don't know ok
Are most of the stars on the HR diagram are classified as which type of star?
stars there called stars
Most of the stars on the HR Diagram are classified as which type of star?
stars there called stars
Where are stars on the hr diagram?
The HR diagram contains only stars - so everywhere.
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.
What types of stars are found on an HR diagram?
All stars.
Where are 90 percent of stars on hr diagram?
main-sequence stars
Why is the hr diagram important to scientist?
The main reason that the HR Diagram is so useful and important to scientists is, you can tell the size of the star by plotting it on the HR Diagram. The different sizes of stars form a pattern on the HR diagram.
What are the smallest stars in the HR diagram?
The red dwarves.
Where are most stars plotted on an HR diagram?
Main sequence
What are the stars located on the left side of the hr diagram like?
They are very hot stars.
Which part of the main sequence in the HR diagram contains the stars that took the longest to reach the main sequence?
The HR diagram does not reference stars on their way to the main sequence, only during or after.
What type of relationship is shown on a HR diagram?
It is a chart showing a scatter chart of stars according to their temperature and their luminosity (or absolute magnitude).
