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.

Are most of the stars on the HR diagram are classified as which type of star?
stars there called stars
Where are most stars plotted on an HR diagram?
Main sequence
Henry Norris Russell and Ejnar Hertzprung?
In the early 20th century, Danish astrophysicist Ejnar Hertzsprung and American astrophysicist Henry Norris Russell independently developed a graph now known as the Hertzsprung-Russell (H-R) diagram, which plots absolute brightness against spectral type. In this diagram, the brightest stars lie near the top of the diagram and the hottest stars lie to the left. On the H-R diagram, most of the stars, including the Sun, fall along a diagonal line that goes from the upper left to the lower right of the diagram. This line called the main sequence.The great majority of stars neighboring the Sun fall on the lower part of the H-R diagram's main sequence, and relatively few lie on the portion of the main sequence above the Sun. This means that most of the Sun's neighboring stars are both cooler and fainter (in absolute magnitude) than the Sun. A smaller population of brighter but cooler stars known as supergiants occupies the uppermost region of the diagram. Some stars, which are difficult to discover because they are so intrinsically faint, lie near the bottom of the H-R diagram. These faint stars are called white dwarfs.
What are the most common types of stars in our universe?
Main-sequence stars; those are stars that are in a certain area in the H-R diagram. They are also the stars which burn (fuse) hydrogen-1, converting it into helium-4.
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).
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 kind is stars are shown along the middle of the HR diagram?
The curve that currently contains most stars on the HR diagram is called the "main sequence". It consists of those stars that fuse hydrogen-1, converting it into helium-4.
Are most of the stars on the HR diagram are classified as which type of star?
stars there called stars

What type of star is most likely to be found on the main sequence?
The curve that contains most stars is called the "Main sequence". The stars on that curve are known as "main sequence stars". Their main characteristic is that they get their energy from fusing hydrogen-1 into helium-4.
Which climate region contains the most big cities?
Temperate climate regions tend to have the most big cities since they offer a more comfortable living environment with moderate temperatures and distinct seasons, which attracts more people to settle and establish urban areas.
Where are most stars plotted on an HR diagram?
Main sequence
What contains most amount of hydroden?
stars
What is the classification of most stars on the H-R diagram?
It's main sequence.
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.
When does the main sequence star phase of a star end?
The "main sequence" is the region (on the HR diagram) for stars which burn hydrogen-1. Once stars use up most of their hydrogen-1 (and have significant amounts of helium-4), they leave the main sequence.
What is the region in an atom that contains most of the mass of an element?
the nucleus
