No, and it is its hydrogen, not helium, that is used up. Hydrogen is fused together to make helium, an inert gas. Helium cannot burn, which is why we use it to fill balloons and not hydrogen. The explosion of the Hindenburg taught us painfully not to use the volatile gas hydrogen in such conditions.
When a star begins to run low on hydrogen, it begins to collapse on itself, burning fuel in the core at a greatly reduced rate. It still has fuel to burn, but it is running low. This superheated core forces the outer atmosphere of the star to expand outward, forming a red giant or supergiant, and that is when the star leaves the Main Sequence. The core still burns, and depending on the mass of the star, the outer envelope will either puff outward in a planetary nebula, leaving a white dwarf behind, or it will explode as a supernova, leaving behind a neutron star or a black hole, depending on the mass of the core.
What else can I help you with?
True or false a main sequence star generates energy by fusing helium into hydrogen?
Oops ! No. The statement is going along pretty good until the end.The star actually fuses hydrogen into helium .
How do you weight a balloon with hellium?
To weight a helium balloon, you can attach small weights to it until it stays grounded. By adding enough weight to counteract the lifting force of the helium, you can measure the weight of the balloon.
After consuming the hydrogen in its core the sun will begin its helium fusion stage swelling until it becomes what type of star?
The sun will swell into a red giant star during its helium fusion stage. This stage occurs when the core contracts and heats up, causing the outer layers to expand and cool, giving the star its red appearance.
Why is the presence of large amounts of helium in the spectrum of a star generally considered to be asign of age?
When stars form they are mostly made up of hydrogen. Main sequence stars derive their energy from converting hydrogen in helium in the cores. As the star ages the ration of helium to hydrogen increases. A star with a lot of helium there for must be old. When the hydrogen has exhausted in the core the star begins to collapse due to gravity until it reaches a point that the temperature of the core is sufficient to fuse Helium into Carbon.
What is the last stage of nuclear fusion for the sun?
Most likely, that will be helium fusion. This is expected to occur when most of the hydrogen in the core has burnt out, and the Sun has expanded into a red giant. The core will then contract, its own weight no longer supported by hydrogen fusion, until the temperature and density has reached sufficient levels to initiate helium fusion. It is expected that the helium fusion will proceed at an initially uncontrolled rate, producing a helium flash. The sun probably has not enough mass to also reach critical levels required for carbon fusion, which would be the next stage in more massive stars.
What process powers most stars including our Sun?
The energy radiated by the Sun comes from nuclear fusiondeep in its core. Main sequence stars like the Sun fuse hydrogen into helium until they exhaust their supply, over billions of years. Eventually they may swell into red giant stars that fuse helium into carbon.
What do stars have to do with nuclear reactions?
The sun and the other stars produce light and heat by the fusion thermonuclear reactions going on in their core. The first full stage of a star's life is the primary phase where it is fusing hydrogen to helium, then helium starts fusing into nitrogen, and so on until iron, at which point the reaction stops.
What day does an elf on the shelf come?
it stays until after Christmas but if you buy it i think it stays forever
What does a performer do off stage?
Wait until they go on stage...
What is the suns next stage after 5 billion years?
Theoretically, in 5 billion years, the Sun will still be in the main sequence. 5.4 billion years (estimated) marks the end of main sequence, where it will be in the intermediary point between a main-sequence star and a post-main-sequence red giant, where it will slowly reach over 200 times it's current mass over the course of about a billion more years, at which point it would be classified as an official red giant and be fully burning helium-4 as a main source of fuel as well as burning a hydrogen shell it built up during the main-sequence. After that point it will eject most of its mass into a planetary nebula and slowly cool as a stellar remnant over the course of a few quadrillion years until it reaches 3K.
