The significance is the following:
1) When lots of stars are plotted in the HR diagram, the vast majority star appear along a curve. This curve is known as the main sequence.
2) It turns out that those are basically the stars that burn hydrogen-1, converting it into helium-4.

∙ 14y agoAn H-R diagram is a graph of stars' luminosity (left side of scale) or absolute magnitude (right side of scale) versus its temperature (at top of scale, hottest left to right) or color (bottom of scale, whiter to the left and red to the right) determined by its relative color and luminosity when compared to the sun of our solar system. In an H-R diagram the sun is given a value of 1 in luminosity and .66 color index (or 5780 Kelvin).
The short answer is the Sun of our solar system.

Where is absolute magnitude indicated on the HR diagram?
its located somewhere
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.
Where does a star spend most of its life on an hr diagram?
On the main sequence.
According to the hertzsprung Russell diagram what color is are sun?
On the HR diagram the Sun's spectrum is of type G2 which makes it yellow.
What color is the most massive type of mainsequence star?
The most massive type of main sequence star on the HR diagram would be indicated by the main sequence area at the top left of the HR diagram, which would be blue or violet in color. Zeta Puppis is an example of such a star. It comes in at 40 solar masses. It is classified as a type "O" star.
What are the colors of the HR Diagram?
The colors of the HR Diagram are:BlueBlue-WhiteYellowOrangeRed-OrangeRed
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.
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 is the brightest star on the Hr diagram?
i don't know about the hr diagram but the brightest star known is r136a1
What chart show is the characteristics of a star?
HR diagram
What are the smallest stars in the HR diagram?
The red dwarves.
What part of the HR diagram are Red supergiant stars in?
Up at the top right. If you look on the Australian Telescope National facility website, their HR diagram shows this clearly.
Why are black dwarfs not on a HR diagram?
Black holes dont appear on HR diagrams because HR diagrams are used to classify stars not find black holes Black holes emit no visible light (are not luminous enough) and therefore do not appear in the HR diagram.
Where is the Sun in the H-R diagram?
Our Sun is a G2V star and will thus appear in the centre of the HR diagram.
What types of stars are found on an HR diagram?
All stars.
