At what stage in star development does a star spend most of its life?
A Star spends most of its life on the "main sequence" of the Hertzsprung-Russell diagram (see related link below). While here it is called a "main sequence" star and its source of energy during this phase of its life is the fusion of hydrogen into helium in its core.
Why is the hr diagram useful in plotting the life cycles of stars?
I don't know ok
What is the main sequence on the Hertzsprung-Russell diagram?
The main sequence on the Hertzsprung-Russell diagram represents the stage in a star's life when it is undergoing nuclear fusion of hydrogen into helium in its core. Stars spend the majority of their lifetime on the main sequence, where they maintain a stable balance between inward gravitational pressure and outward radiation pressure. The main sequence runs diagonally from high temperature, high luminosity stars (top left) to lower temperature, lower luminosity stars (bottom right).
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.
Will a very bright star on the HR diagram most likely have positive or negative magnitude?
Positive - most of them are far away.
Will a star spend most of its life as a protostar?
No, it will spend most of it's life as a main sequence star.
Where does a star spend most of its lifetime on the h-r diagram?
On the main sequence.

Where does a star spend most of its lifetime on an h r diagram?
MAIN-SEQUENCE The average star spends 90% of its life as a hydrogen burning MS star.
Do Stars spend most of their life span as main-sequence stars?
Yes Star spend most of their life span as a main sequence star. A star end will depend on its size in life the end of a start can be a red giant to supernova, a white dwarf, pulsar, or black hole.
A star spends most of its life in what stage?
A star whilst being luminous, will spend most of it's life - about 90% - on the main sequence.However, when a star "dies" they are still refereed to, by many, as stars so one could argue that a star will spend more time "dead" than "alive".So you could say that a star spends most of it's life as a stellar remnant.If this is a homework question, the answer is Main Sequence.
Most of the stars on the HR Diagram are classified as which type of star?
stars there called stars

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.
