A supernova is a star saying "The End". The H-R diagram shows they different types of stars by spectral class, color, etc. It was never intended to show the ending of stars. On most H-R diagrams, you will find at the top, or occasionally top right, a place for "Supergiants". Some of those stars will eventually become supernovas. To be absolutely clear: A supernova isn't a type of star - it is the "end" of a type of star.

Which part of the hertzsprung Russell diagram is occupied by protostars?
Whilst the surrounding matter is falling into the central region, it is considered to be in the protostar stage and thus is not on the HR diagram However, when the surrounding gas/dust envelope disperses and the accretion process stops, the star is then considered as a pre-main sequence star. In the HR diagram, the star would then appear on the stellar birthline at the bottom right hand corner.
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.
Why are there no black holes or neutron stars on the H R diagram?
The Hertzsprung--Russell diagram is a scatter graph of stars showing the relationship between the stars' absolute magnitudes or luminosities versus their spectral types or classifications and effective temperatures.Because the luminosity is low or non existent in the case of black holes, they do not appear on 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.
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 are cool red giant stars on the H-R?
Depending on the luminosity they will appear to the right of the HR diagram.
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
Where is the Sirius star on h-r diagram?
Sirius is a binary star. Sirius A has a spectral type of A1V and will appear on the HR in the top left corner. Sirius B has a spectral type of DA2 and will appear on the HR in the bottom left corner as a white dwarf.
Can black holes appear out of no where?
no because black holes can only form through supernovas.
