What else can I help you with?
The star begins to run out of fuel and expands Into a red giant or red super giant?
No. That is when stars run out of hydrogen. They then have helium for fuel.
What is an old star of average size that has begun to expand and cool as its fuel has begun to run out?
Red giant.
What does it mean when a star goes off the main sequence?
When a star "goes off the main-sequence" it generally means the star has run out of hydrogen fuel and is beginning the post-main-sequence or its end of life phase. The main sequence of a star is the time where it is no longer just a proto-star but is burning hydrogen as a primary source of fuel.
What happens when a neutron star runs out of fuel?
Neutron stars do not have fuel. A neutron star is a remnant of a star that has already died.
Why does the main sequence star end?
A "main-sequence star" is one that fuses hydrogen into helium. Eventually, the star will run out of this specific type of fuel - in other words, it won't have enough hydrogen (at least, near its core) to continue this process.
When a neutron star runs out of fuel what does it become?
A neutron star is already the remains of a massive star that has run out of fuel.
The star begins to run out of fuel and expands Into a red giant or red super giant?
No. That is when stars run out of hydrogen. They then have helium for fuel.
Are white dwarfs a type of star?
Yes. A white dwarf is a compact star, the remnant of a star that has run our of fuel.
Why do all-star eventually die?
They will all eventually run out of fuel.
Which event in the life cycle of a star causes it to begin to grow?
This will happen when the star starts to run out of hydrogen fuel.
Is a dwarf star one that has no fuel to make its own energy?
Yes, that is correct. A white dwarf has run out of fuel - it used it up.Yes, that is correct. A white dwarf has run out of fuel - it used it up.Yes, that is correct. A white dwarf has run out of fuel - it used it up.Yes, that is correct. A white dwarf has run out of fuel - it used it up.
About how many years does it take for a star to run out of its fuel hydrogen?
It typically takes around 10 billion years for a star like the sun to consume all its hydrogen fuel and enter a different phase of its life cycle. The exact duration can vary depending on the size and type of the star.
What is produced by rapid contraction of a very heavy main sequence star that run out of fuel?
Supernova
What is produced by rapid contraction of a very heavy main sequence star that has a run out of fuel?
Supernova
What is produced by rapid contraction of a very heavy main sequence star that has run out of fuel?
Supernova
Is white dwarf a dead star?
Yes - in the sense that it no longer produces energy. In other words, the star has run out of fuel for nuclear fusion.
What is an old star of average size that has begun to expand and cool as its fuel has begun to run out?
Red giant.
