Many stars which are members of an open cluster are blue, hot stars, with relatively short life expectancies (a few hundred thousand years to a couple of million years life).

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.
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
What does the main sequence stars on the hr diagram represent?
Based on initial size and chemical composition a star will enter a band on the HR diagram as a mains sequence star. Stars on the main sequence are in equilibrium from thermal pressure trying to enlarge the star and gravitational pressure trying to collapse the star. Stars on the main sequence range from massive hot blue-white stars to much less massive red stars.
Where are stars on the hr diagram?
The HR diagram contains only stars - so everywhere.
Which region contains the most stars in the HR Diagram?
Several regions of the HR diagram have been given names, although stars can occupy any portion. The brightest stars are called supergiants. Star clusters are rich in stars just off the main sequence called red giants. Main sequence stars are called dwarfs.
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.
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
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.
