it depends on what type of star it is bigger stars run out of fuel hydrogen faster then smaller stars

Why does a star's hydrogen supply run out?
The nuclear fusion in a star's core converts hydrogen into helium. Therefore the amount of hydrogen in a star is constantly decreasing.
Is it possible to convert hydrogen into oxygen?
Strictly speaking No, however it would be possible inside a star but the star would have to spend millions of years changing the hydrogen into helium, then other bigger elements ect before it becomes oxygen
What is the first element that is converted in a star's core?
Hydrogen into Helium.
How long do main sequence stars live?
A main sequence star is a star that is fusing hydrogen in its core. Stars leave the main sequence when they run out of hydrogen and start to fuse heavier elements (starting with helium and finishing with iron). The length of time a star remains on the main sequence depends on how massive the star is. The larger the star the more gravity it has and the tighter this gravity squeezes the core - this makes the core hotter and brings the hydrogen atoms closer together so the fusion process proceeds more rapidly. Thus big stars will only spend a few tens of millions of years on the main sequence while stars the size of our sun will spend ten thousand million years on the main sequence, and smaller stars (red dwarf stars) will spend trillions of years fusing hydrogen.
Is it true that an average star spends 90 percent of its life as a helium burning main sequence star?
no, as a hydrogen burning main sequence star.
What is star fuel?
hydrogen
What happens when a star burns all of its hydrogen?
When a star burns up all of its hydrogen,it becomes red in color.As hydrogen is the fuel for star and it will burst after it.
What is a star's main source of fuel?
Hydrogen
What happens when a star burns up all of its hydrogen?
When a star burns up all of its hydrogen,it becomes red in color.As hydrogen is the fuel for star and it will burst after it.
What is the name of the portion of a stars life were it uses hydrogen as fuel?
A star that uses hydrogen as fuel is a main sequencestar.
What is a star's main fuel during its lifetime?
hydrogen
Name of fuel that make the star glow?
Hydrogen
What is the name for the portion of a star's life cycle when it uses hydrogen for fuel?
When a star is in the Hydrogen burning phase it said to be a Main Sequence star.
Why does the amount of hydrogen in a star decrease?
Because Hydrogen is the fuel of Stars, hydrogen consumed and Helium is formed.
What begins the death of a star?
Usually the fact that the star runs out of fuel.
When a star runs out if hydrogen what does it use as fuel source?
helium
What Star Expands After Exhausting Its Hydrogen Fuel?
Red Giants:)
