What is an expanding star after exhausting its hydrogen fuel called?
A Red Giant or a Red Super Giant if it is very large.
Why do some stars become white dwarfs and others become neutron stars and black holes?
Actually if a star is medium or low mass is will run out of fuel and turn into a red giant, once the stars atmosphere slowly drifts away and the core is remaining it will eventually become a white dwarf For more massive stars it will turn in to a super giant the will cause a supernova, after the supernova the star can either a black hole or a neutron star
How is a stellar mass black hole formed?
A stellar black hole forms when a massive star exhausts the fuel in its core. The core then collapses. If it has enough mass nothing will be able to stop the collapse and the core will form a black hole. The outer layers of the star will, in most cases, be blaster away in a supernova explosion.
What is the correct order of a life cycle of a star?
At the beggining, a star starts out as a nebula. This nebula's gas condenses to form the sun. This sun is called a protostar. When all of the hydrogen is used up in nuclear fusion to produce helium, the star begins to grow and gets to a stage known as the red giant stage. At this point, depending on the size of the star at this point, it can form differently. It can either become a super giant or a dwarf star. When the red giant become a dwarf star, it had collapsed in onitself after burning all possible fuel. It will continue to glow until it reaches its final phase as a black dwarf, which doesn't produce any light and is in a dormant phase. If the red giant becomes a super giant, then it will continue to grow until it burns off all of its fuel and collapses in on itself, where it then explodes into a supernova. If this supernova condenses to quickly, it will form a black hole.
What is the length of a reactor core with 1 cm diameter fuel rods?
Specifying the diameter of fuel rods (1 cm) does not really allow estimates of the length of the reactor core in which they are used. (How many rods in a fuel bundle, and how many fuel bundles in the core?) Keep in mind that the core will end up in a shape that is engineered to use the fuel most efficiently. This means that really short and fat core geometry is out, and so is long skinny geometry. The ideal core shape will probably end up roughly cylindrical, and perhaps with it being roughly as long as its diameter. If you have a lot of fuel rods in a lot of fuel bundles, then they will be longer than a more modest amount of fuel rods in a smaller number of bundles. A reactor core in a shape that approximates a soda can or tuna can is going to be avoided, and a shape somewhat more like a soup can is better. Of the first two, the former would be a bit too long, and the latter too short. The "soup can" geometry will support better operation, more even fuel burn, and more desirable operating characteristics.
How is the red-giant formed?
A red giant forms when a star runs out of hydrogen fuel at its core and starts fusing hydrogen in a shell around the core the core. This causes the star to expand and cool.
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 expanding star after exhausting its hydrogen fuel called?
A Red Giant or a Red Super Giant if it is very large.
The sun will eventually use up its hydrogen fuel and become what?
When the sun exhausts the hydrogen in its core and become a red giant.
What is the difference between a red supergiant and a red giant?
A red supergiant is the largest type of star by volume, but not by mass. It is also one of the"coolest" active stars. These stars have fused most of their hydrogen to helium, and pressure from its core have swelled its size, to between 200 and 800 times the diameter of our Sun. Since the mass has not increased with the volume, the star's average density is comparatively low.
When a main-sequence star has exhausted the fuel in its core it becomes a....?
I am pretty sure it becomes a giant if I'm not mistaken.
When a main sequence star runs out of hydrogen to fuel the core of which type of star begins to form?
red giant
When a main sequence star has the fuel in its core it becomes?
The next step in its life is to become a "red giant" star.
When a main sequence has exhausted the fuel in its core it becomes?
The next step in its life is to become a "red giant" star.
How a star becames a white dwarf?
A white dwarf is the core of a dead star. As the star runs out of fuel, it expands into a red giant, as the shell of the red giant became a planetary nebula, and the core shrinks and became a white dwarf.
When a main sequence star runs out of fuel it becomes a?
Either a giant or a super giant. Giants will eventually collapse on its core and have a little white dwarf left behind, but they will have the same mass and gravity as the old star. Supergiants will collapse but in an explosion, supernova, and they will either become a nuetron star or a black hole.
When a main-sequence star has exhausted the fuel in its core it becomes a .?
The next step in its life is to become a "red giant" star.
