Why do supernovas not appear on the HR diagram?
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.
Where does a star spend most of its life on an hr diagram?
On the main sequence.
What is the HR diagram based on?
The Hertzsprung-Russell (HR) diagram is based on plotting a star's luminosity against its temperature or spectral type. This diagram helps astronomers classify stars based on their evolutionary stage and enables them to study relationships between a star's properties such as temperature, luminosity, and size.
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.

What chart show is the characteristics of a star?
HR diagram
How to read an HR diagram and interpret the data it presents?
To read an HR diagram, look at the stars' luminosity on the vertical axis and their temperature on the horizontal axis. The main sequence represents stars in stable fusion. Interpret data by noting a star's position on the diagram to determine its temperature, size, and stage of evolution.
Where does a star spend most of its life on an hr diagram?
On the main sequence.
What information is need to plot a star on h-r diagram?
You need to know the luminosity and temperature of star in order to plot it on the HR diagram.
When a star changes its position in the HR diagram it is because the star is?
evolving into a later stage. For example, a G2 star going into a red giant (M type)
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.
What type of star has a high temperature and a high luminosity in the hr diagram?
White dwarfs.
Most of the stars on the HR Diagram are classified as which type of star?
stars there called stars
What type of star has a high temperature and high luminosity in the HR diagram?
