What is a large cool star form when a star runs out of hydrogen?
red giant
Reaction dead star?
A dead star is one that no longer experiences nuclear fusion. This happens when a star runs out of hydrogen it can use to convert to helium.
The energy source of stars is primarily associated with?
hydrogen fusion in the core. eventually runs out of hydrogen in the core and hydrogen fusion moves to the shell whilst the core contracts (star expands into red giant)...star leaves the main sequence.
How is a star able to begin helium fusion after it ran out of hydrogen?
The basic idea is that once a star runs out of hydrogen fuel, it starts contracting until it gets hot enough to fuse helium into heavier elements. This happens at temperatures that are quite a bit higher than the temperatures required to fuse hydrogen into helium.
What star in the life cycle of stars fuses hydrogen and helium?
A "red giant" star can fuse both hydrogen (in the star's outer shells) and helium (in the core).
What is a large cool star form when a star runs out of hydrogen?
red giant
A large cool star formed when a star runs out of hydrogen?
red giant
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
When a main sequence star runs out of hydrogen to the core which type of star begins to form?
red giant
When a main sequence star runs out of hydrogen to fuel the core of which type of star begins to form?
red giant
Reaction dead star?
A dead star is one that no longer experiences nuclear fusion. This happens when a star runs out of hydrogen it can use to convert to helium.
The energy source of stars is primarily associated with?
hydrogen fusion in the core. eventually runs out of hydrogen in the core and hydrogen fusion moves to the shell whilst the core contracts (star expands into red giant)...star leaves the main sequence.
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.
What element is the fuel for main-sequence star?
Stars a giant balls of gas mainly hydrogen and helium. inside a star there are such temperatures that hydrogen fusion occurs making helium and when the star runs outta hydrogen it gets hotter and helium fusion occurs then carbon fusion etc etc. so ultimately it depends on the age of the star.
A star the size of your Sun continues its fusion for approximately 10 billion years until the supply of hydrogen runs out The amount of hydrogen required to keep up that process indicates that?
Hydrogen is extreamly abundant.
When does the main sequence star phase of a star end?
The "main sequence" is the region (on the HR diagram) for stars which burn hydrogen-1. Once stars use up most of their hydrogen-1 (and have significant amounts of helium-4), they leave the main sequence.
