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.
How does the main-sequence lifetime of a star compare to its entire fusion lifetime?
The main-sequence lifetime is a phase in a star's life when it fuses hydrogen into helium in its core. This phase typically lasts about 90% of a star's total fusion lifetime. After the main sequence, a star may continue to fuse other elements, depending on its mass, which will determine the total duration of its fusion lifetime.
Where is the Sun in the H-R diagram?
The Sun is located on the main sequence of the H-R diagram, which is where stars like the Sun reside for most of their lifetime. It falls in the middle of the main sequence, representing a stable phase of hydrogen fusion in its core.
Are most of the stars on the HR diagram are classified as which type of star?
stars there called stars
Protostar will turn into what kind of star?
Protostars will eventually evolve into main sequence stars, where they will spend the majority of their lifetime fusing hydrogen into helium in their cores. The exact path of evolution will depend on factors such as mass, temperature, and composition.
Where does a star spend most of its lifetime on an h r diagram?

Where does a star spend most of its life on an hr diagram?
On the main sequence.
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.

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).
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.
What does a star primarily burn in its lifetime?
Most stars, for most of their existence, fuse hydrogen into helium.
How does a star's mass indicate lifetime?
When a star is at the end of its lifetime its mass increases.
How long does an massive star live?
The lifetime of a star varies a lot, depending on its exact mass. The lifetime of a star can be anywhere from just a few million years for the most massive stars, to trillions of years for red dwarves.
What dose the lifetime of a star depend on?
Mainly its mass. The most massive stars develop the most quickly.
How does the mass of a star relate to the time it stays on the Hertzsprung Russell diagram?
The mass of a star affects its location and lifespan on the Hertzsprung-Russell diagram. Generally, more massive stars are hotter, brighter, and have shorter lifespans, while less massive stars are cooler, dimmer, and have longer lifespans. The relationship between mass and time on the diagram is intricately linked to the star's fusion processes and how it evolves over its lifetime.
