- Supernova nucleosynthesis. Supernova nucleosynthesis is a theory of the production of many different chemical elements in supernova explosions, first advanced by Fred Hoyle in 1954. The nucleosynthesis, or fusion of lighter elements into heavier ones, occurs during explosive oxygen burning and silicon burning processes. Those fusion reactions create the elements silicon, sulfur, chlorine, argon, sodium, potassium, calcium, scandium, titanium and iron peak elements: vanadium, chromium, manganese, iron, cobalt, and nickel.

Supernovae: Catastrophic Explosions of Giant Stars There are some variations of this type of supernova, such as the merger of two white dwarfs (instead of the accretion of material from a main sequence star). It is also thought that type I supernovae encapsulate the infamous gamma-ray bursts (GRBs).nce a star leaves the main sequence it will follow a particular path that depends on its mass. For type I supernovae, we are concerned with stars that are no more than about 1.4 times the mass of our Sun.

How Stars Work Stars More Massive Than the Sun When the core runs out of hydrogen, these stars fuse helium into carbon just like the Sun. However, after the helium is gone, their mass is enough to fuse carbon into heavier elements such as oxygen, neon, silicon, magnesium, sulfur and iron. Once the core has turned to iron, it can burn no longer.

- When a red giant star has changed all of its helium into carbon and oxygen, it then begins to turn the carbon and oxygen atoms into iron Atoms. Iron is the heaviest kind of atom that a star can make, so when a star has made most of its carbon and oxygen into iron, it becomes a supernova and explodes.hen the supernova explodes, it shoots out carbon, oxygen, and iron atoms all over the Universe, and eventually gravity sucks these atoms into new planets like Earth. All of the iron on Earth was originally inside stars.

- During the red supergiant phase, the largest stars in the universe fuse many heavier elements in addition to helium, such as carbon, neon, and silicon. In fact, these giant stars are necessary to provide the heavy elements, which are essential for the formation of galaxies.

Nuclear fusion Further elements might also be fused, and other scientists had speculated that stars were the crucible in which light elements combined to create heavy elements, but without more accurate measurements of their atomic masses nothing more could be said at the time.

Supernovae These blasts produce much of the material in the universe—including some elements, like iron, which make up our planet and even ourselves. Heavy elements are only produced in supernovae, so all of us carry the remnants of these distant explosions within our own bodies.Supernovae add enriching elements to space clouds of dust and gas, further interstellar diversity, and produce a shock wave that compresses clouds of gas to aid new star formation.hese blasts produce much of the material in the universe—including some elements, like iron, which make up our planet and even ourselves.

Exploding Star: New Supernova Discovery Is Closest in Years Astronomers from Caltech have confirmed the supernova and classified it as a young, reddened Type Ia supernova. These kinds of objects are thought to originate in a close binary system where at least one star is a white dwarf, or a small, dense core of a star that has ceased undergoing nuclear reactions.

- There are two types of white dwarf stars; - low mass s … tars with a solar mass less than 0.5 will become helium white dwarfs. The temperature of these will not be high enough to fuse helium into carbon.- low to medium stars with a solar mass between 0.5 and 8 will become Carbon-Oxygen white dwarfs.es and No. White dwarfs generally form from stars that have too low a mass to become supernovae. However, if the white dwarf has a companion star, it is possible for the white dwarf to accrete additional fuel from the neighboring star and then it can explode as a nova {See Link} or a Supernova type La [See link].

Cause of Supernova SN 1006 Revealed However, an explosion produced by the merger of two white dwarfs leaves no trace, except for the supernova remnant that can be studied until centuries later, as in the case of SN 1006, one of only four historical supernovae of this type that have occurred in the Milky Way.

Stars Main sequence stars over eight solar masses are destined to die in a titanic explosion called a supernova. A supernova is not merely a bigger nova. In a nova, only the star's surface explodes. In a supernova, the star's core collapses and then explodes. In massive stars, a complex series of nuclear reactions leads to the production of iron in the core.

- Most stars eventually grow old and die, but a few are large enough to burst into supernova. The stellar life cycle is essentially the same for most stars, hence it is a cycle even though the process does not truly repeat. In the event of supernova explosions, the material can be gathered to form a new, second generation star, but this star will be rife with heavier elements than the progenitor star.

What Causes a Supernova Explosion? A Supernova Explosion in Process. A supernova occurs when a super massive star explodes. It is a dramatic end to a star’s life. Supernovae (which is the plural form of supernova) become very bright and cause an enormous burst of radiation that can outshine an entire galaxy before disappearing.

Stars, Galaxy and the Universe Type Ia supernovas happen when a white dwarf star is orbiting a big star. Sometimes, the white dwarf star sucks matter off of the big star. When the white dwarf gets to be about 1.4 times the mass of the sun, it collapses.This makes lots of energy and light, which is why supernovas are very bright.ype Ia supernovas happen when a white dwarf star is orbiting a big star.

- All living things-both plants and animals-also contain iron. Plants use iron to help them pull energy from sunlight through their leaves, and animals (including people) use iron to move oxygen through their bodies and bring energy to their cells.hen the supernova explodes, it shoots out carbon, oxygen, and iron atoms all over the Universe, and eventually gravity sucks these atoms into new planets like Earth. All of the iron on Earth was originally inside stars.

Chemical element In general, such elements up to iron are made in large stars in the process of becoming supernovas. Iron-56 is particularly common, since it is the most stable element that can easily be made from alpha particles (being a product of decay of radioactive nickel-56, ultimately made from 14 helium nuclei). Elements heavier than iron are made in energy-absorbing processes in large stars, and their abundance in the universe (and on Earth) generally decreases with their atomic number.

Formation of the High Mass Elements Stars have enough hydrogen to maintain their energy output for millions of years. During most of a star's lifetime, hydrogen nuclei fuse together to form helium nuclei. As the star runs out of hydrogen, other fusion reactions take place forming the nuclei of other elements [element: A substance made of one type of atom only.]. Heavier elements than hydrogen and helium (up to iron) are formed.

White dwarf Usually, therefore, white dwarfs are composed of carbon and oxygen. If the mass of the progenitor is between 8 and 10.5 solar masses (M☉), the core temperature is sufficient to fuse carbon but not neon, in which case an oxygen-neon– magnesium white dwarf may be formed.f a red giant has insufficient mass to generate the core temperatures required to fuse carbon, around 1 billion K, an inert mass of carbon and oxygen will build up at its center. After shedding its outer layers to form a planetary nebula, it will leave behind this core, which forms the remnant white dwarf.

- The Sun does not have enough mass to become a supernova because its mass is less than the Chandrasekhar mass (approximately 1.4 Suns) and it has no way to gain mass.When the Sun comes to the end of its life (In about 5 billion years) [See Link] it will slowly emerge into a red giant.es, if it's large enough, a star needs to be at least 1.4 times the mass of our sun to have a chance at becoming a supernova.    The color of a star changes through it … 's lifetime, typically starting off as blueish, then becoming yellow, and finishing its life as a red giant.

- Type Ia supernovas, in contrast, are observed in all kinds of galaxies, and are produced by white dwarf stars, the condensed remnant of what used to be sun-like stars. A white dwarf star, a dense ball primarily composed of carbon and oxygen atoms, is intrinsically the most stable of stars, as long as its mass remains below the so-called Chandrasekhar limit of 1.4 solar masses.

- Most of the gas — about 72 percent — is hydrogen. Nuclear fusion converts hydrogen into other elements. The sun is also composed of about 26 percent helium and trace amounts of other elements — oxygen, carbon, neon, nitrogen, magnesium, iron and silicon. These elements are created in the sun's core, which makes up 25 percent of the sun. Gravitational forces create tremendous pressure and temperatures in the core. The temperature of the sun in this layer is about 27 million degrees F (15 million degrees C).

- All the elements on Earth were formed in the heart of exploding stars. The early Universe was made of just two elements, hydrogen and helium, which formed into stars. At the fiery core of these stars, the hydrogen and helium were forced together to form new, heavier elements. Even heavier elements were created in the explosions of massive stars, called supernovas.

Type II supernova Type Ib and Ic supernovae are a type of core-collapse supernova for a massive star that has shed its outer envelope of hydrogen and (for Type Ic) helium. As a result, they appear to be lacking in these elements.

Supernova Since a supernova can occur whenever the mass of the star at the time of core collapse is low enough not to cause complete fallback to a black hole, any massive star may result in a supernova if it loses enough mass before core collapse occurs.
