After a star has converted most of its Hydrogen into Helium, it can no longergenerate the energy to maintain its size against its own gravity and begins to contract. This contraction heats of the interior and if the heat is great enough (because the star is massive enough) it can begin a new fusion process, turning Helium into Carbon. However, this process is nowhere as efficient as the Hydrogen-Helium one and a star in this stage will only last a small fraction of the time it spent as a H-He factory.
Soon (cosmically speaking), the Helium will be exhausted and a new contraction will begin, which MAY, if the mass is enough, start a new fusion process with the Carbon to produce Oxygen, Neon, Silicon. Each stage is less efficient than the one before and when the star starts making Iron, its on its last cycle. Turning Iron into other elements CONSUMES energy rather than releases it.
In exceptional cases, the mass of the star may be great enough that the Iron is put to what is rather inelegantly called "Maximum Scrunch," and it rebounds with a burst of neutrinos followed by a stellar explosion we call a Supernova. Supernovae are responsible for making all the elements more complex than Iron.
What else can I help you with?
What type of star would helium be converted to carbon as the final stage of fusion?
Helium is converted into carbon during the final stage of fusion in a star called a red giant. This process occurs when helium fusion in the core of the star gives rise to carbon as the result of nuclear reactions.
What elements are in the star Aldebaran?
Hydrogen, helium, carbon dioxide, and calcium.
What happens to a star when the outward force of fusion is less than the inward force?
the star collapses in on itself, and usually when the fusion stops it is in the last stages of its life as a giant or supergiant and forms a white dwarf made of the carbon left over from the second stage of helium to carbon fusion from the core of the star that takes place after the hydrogen to helium fusion. after the white dwarf is formed it will eventually cool off into a black dwarf which is basically a carbon corpse of a star
What is the composition of antares?
Antares is a red supergiant star composed mostly of hydrogen and helium, with traces of heavier elements like carbon, oxygen, and nitrogen. Its outer layers are cooler, which give the star its distinctive red color.
What type of star is alpha cancri?
Alpha Cancri is a binary star system consisting of two stars: one is a yellow giant star and the other is a white dwarf. The primary star is a K-type giant star, also known as a "Carbon star," while the second star is a compact, hot white dwarf.
What is a star composed of carbon and nitrogen?
A star composed of carbon and nitrogen would likely be a red giant or supergiant in the later stages of its life cycle. These elements are produced through nuclear fusion processes inside the star's core as it evolves. The presence of carbon and nitrogen can affect the star's temperature, luminosity, and ultimately its fate.
At what temperature does a star's core reach Carbon detonation?
Temperatures in the star's core can reach 3x109 K.
What type of star would helium be converted to carbon as the final stage of fusion?
Helium is converted into carbon during the final stage of fusion in a star called a red giant. This process occurs when helium fusion in the core of the star gives rise to carbon as the result of nuclear reactions.
What are the gasses called around a dying star?
carbon dioxide
What elements are in the star Aldebaran?
Hydrogen, helium, carbon dioxide, and calcium.
Which nuclear fusion cycle is the next one to begin after helium fusion ends in a massive star?
The next nuclear fusion cycle after helium fusion in a massive star is carbon fusion. This process involves fusing helium nuclei to form carbon. Carbon fusion typically occurs in the core of a massive star after helium fusion is completed.
What happens when a medium star's temperature reaches 200000000 degrees Celsius?
helium atoms fuse to form carbon atoms in the core of the star
What element is made when you fuse 2 carbon molecules?
Actually fusing carbon, such as in a star will create one of several type of elements. In the vast majority of stars carbon is not fused at all, but depending on the star's mass carbon may fuse into neon, oxygen, magnesium, among a couple others. This happens in specific type of stars, at specific times in their lives. Fusing is different from chemical reactions. There are no chemical reactions that can make elements, but with nuclear transmutation you can do it. For example, in a star hydrogen is fused into helium, and sometimes helium into carbon.
What happens to a star when the outward force of fusion is less than the inward force?
the star collapses in on itself, and usually when the fusion stops it is in the last stages of its life as a giant or supergiant and forms a white dwarf made of the carbon left over from the second stage of helium to carbon fusion from the core of the star that takes place after the hydrogen to helium fusion. after the white dwarf is formed it will eventually cool off into a black dwarf which is basically a carbon corpse of a star
What is in a star's core?
A star's core consists mostly of hydrogen. As the star ages, the amount of helium, carbon and other elements in the core increases as they are the result "ash" resulting from the consumption of the hydrogen fuel.
What is the composition of antares?
Antares is a red supergiant star composed mostly of hydrogen and helium, with traces of heavier elements like carbon, oxygen, and nitrogen. Its outer layers are cooler, which give the star its distinctive red color.
Why can't a lower-mass star generate energy through carbon flash?
Lower-mass stars do not have enough pressure and temperature at their cores to trigger the carbon flash phenomenon, which is necessary for carbon to begin fusion into heavier elements. Carbon flash occurs in higher-mass stars that have undergone helium fusion to build up a core of carbon. Lower-mass stars typically do not reach this stage of fusion.
