Does nuclear fusion occurs as stars cool down?
The star will continue to fuse hydrogen until it runs out of resources and dies out, after which it will collapse and die.
Why doesn't nuclear fusion take place in a white dwarf?
Nuclear fusion doesn't take place in a white dwarf because the core temperature and pressure aren't high enough to initiate the fusion of heavier elements such as carbon and oxygen. White dwarfs have already exhausted their nuclear fuel and are essentially the leftover cores of stars that have gone through their fusion stages.
What does nuclear fusion look like?
Nuclear fusion itself is not visible to the naked eye as it occurs at the atomic level. However, in controlled fusion experiments, the release of energy produces intense heat and light, creating a distinctive glow or plasma that can be observed. This plasma is often described as a vibrant, swirling mass of glowing gas.
What is the difference between red and brown dwarf stars?
Red dwarf stars are massive enough to undergo nuclear fusion, so they would burn a long time before they run out of fuel. Brown dwarves are not massive enough for nuclear fusion, so almost all of its light come from the time when the brown dwarf was formed. Over a long period of time, a brown dwarf would cool down into a gas giant similar to Jupiter.
What elements are formed in cool stars?
In cool stars, elements such as hydrogen and helium are primarily produced through nuclear fusion in their cores. Elements heavier than helium (e.g., carbon, oxygen, and iron) are formed through nucleosynthesis processes during the later stages of a star's lifecycle, such as in red giant stars or during supernova events.

What is a loop of relatively cool incandescent gas that extends above the photosphere?

Does a white dwarf star use hydrogen for energy?
No, white dwarf stars do not undergo nuclear fusion like main sequence stars, including our Sun. White dwarf stars are the remnants of low to medium mass stars, and they use stored thermal energy to shine and gradually cool over time.
If a protostar doesn't undergo a nuclear fusion what will it turn into?
If a protostar does not undergo nuclear fusion, it will not become a star. Instead, it will either become a brown dwarf, which is a failed star that lacks the mass to sustain nuclear fusion, or it will simply cool down into a cold, dense object known as a sub-stellar object.
How does fusion happen?
in dbz they do a special dance kakarotto and vegeta fuse into gogeta then later they fuse into vigito in fusion reborn they fuse into gogeta.i think fusion reborn is cool because all the villins come back alive like raditz,naapa,janemba,frieza,king cold,cooler,zarbon,dodoria,zorn the red ribbon army,bojack and so many other villins its so cool
3 advantages nuclear fusion has over nuclear fission?
The binding energy (Strong Atomic Force) released is much greater when fusion occurs than when fission occurs. As an example, that is why fission bombs typically have yields around 100 to 500 kilotons of equivalent TNT, while fusion bombs typically have yields in the 25 to 50 megaton range. The problem is that fusion requires a lot of energy to initiate - in fact, most fusion bombs use a fission bomb to set them off.
Red giant is a luminous giant star of low or intermediate mass that is in a late phase of its evolution with nuclear fusion going on in a shell outside the core but not in the core itself?
Thermonuclear fusion is still going on in the core of a red giant, but it is a different type of thermonuclear fusion. The center of the core has reached high enough temperature and pressure that it can now burn helium, producing carbon. 3 4He --> 12C The large amount of energy released by this type of fusion pushes the outer layers away, making a giant star. The expansion of volume of the surface layer causes it to cool, appearing red. Thus a red giant.
Where do stars begin their lives?
Stars begin their lives as clouds of gas and dust called nebulae. Within these nebulae, gravity causes the gas and dust to collapse and heat up, eventually leading to the ignition of nuclear fusion in the core, which marks the birth of a star.
