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.

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.
On a Hertzsprung-Russel diagram red giants and supergiants are positioned?
above the main-sequence stars
A diagonal pattern on an H-R diagram where most stars lie is called?
main sequence
What does the main sequence star represent?
A main-sequence star is one that is along a curve where the majority of stars are located, when plotted in an H-R diagram. It is a star that gets its energy from fusing hydrogen-1 into helium-4.
The region of the Hertzsprung-Russell diagram with the most stars is the what?
The main sequence - the region across the middle of the diagram.
What is a diagonal band of stars on the H-R diagram?
Main sequence 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.
Why do most stars characteristics make them appear on the main sequence on the HR diagram?
I assume the different points on the main sequence represent a kind of balance for the case of hydrogen-to-helium fusion.
What do you understand by main sequence stars?
In the HR-diagram, a diagram of color vs. luminosity, most stars are concentrated close to one curve, called the "main sequence". It turns out that stars on the main sequence are the stars that mainly get their energy by converting hydrogen into helium.
Where are 90 percent of stars on hr diagram?
main-sequence stars
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).
On a Hertzsprung-Russel diagram red giants and supergiants are positioned?
above the main-sequence stars
About 90 percent of the stars on the hertzsprung-Rusell diagram are?
Main-sequence stars
Where are most stars plotted on an HR diagram?
Main sequence
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 is the color of a main sequence star?
As the HR diagram shows, the hottest stars on the main sequence range from 30,000K as blue-white stars to about 3,000K as redish stars.
A diagonal pattern on an H-R diagram where most stars lie is called?
