It is the elements heavier than iron that are formed in a supernova. All the heavier elements up through uranium appear when a star of sufficient mass collapses in a supernova event. These heavier elements, sometimes referred to as the trans-iron elements, appear in the collapse of a massive star. In this catastrophic event, the iron and silicon (and any other lighter elements) in the star are super compressed. The already hot conditions are made even hotter, and the available energy is sufficient to drive the fusion reactions that create the trans-iron elements.

All the fusion reactions up through those that create iron are exothermic, and that means they release energy. The fusion reactions that create the trans-iron elements are endothermic, and that means energy has to be put into them. Only in the collapse of a star of sufficient mass is there enough energy to drive the fusion reactions that produce the trans-iron elements.

See Periodic Table (iron is number 26).

During a nova, elements up to iron are formed through nuclear fusion of lighter elements in the outer layers of the star. In a supernova, elements heavier than iron are formed through rapid neutron capture processes, such as the r-process and s-process, occurring during the explosion. This leads to the creation of elements like gold, platinum, and uranium.

Depending on the original mass of the star, either a neutron star or a black hole.

It depends on the type of supernova. A supernova 1a would be mostly hydrogen, where as a type II supernova would have little hydrogen and alot of the other gases.

Where are all the elements heavier than iron formed?

They are usually first formed in supernova explosions. These would be dispersed in space and might end up in a planetary system..The heavier, radioactive, nuclei would then form their daughter elements.


What is the final explosion of a dying supergiant star called?

A supernova, or in the case of a smaller star, a nova.


Can supernova's turn into black holes?

yes, nothing can be overweight in the universe....... even super nova! when supernova becomes very very heavy then it explodes, hence the vacuum formed inside becomes the birth of black hole. Nikhil Swami nikhilswami1@gmail.com


How is the gold in a wedding ring evidence of ancient stars that ran their life cylcles long before the solar system came into being?

Gold is formed from the fusion of neutron stars, which are remnants of massive stars that have exploded billions of years ago. The elements found in gold, like those produced in neutron star collisions, have to be synthesized through extreme processes beyond what regular stars can create. So, the presence of gold in a wedding ring is a direct link to the cosmic events that occurred long before our solar system's formation.


How do the elements of the whole periodic table relate to the lifecycle of a star?

Elements in the periodic table are formed through nuclear fusion processes within stars. As a star progresses through its lifecycle, it fuses lighter elements into heavier ones. Elements up to iron are primarily formed in the cores of stars, while heavier elements are produced during supernova explosions. These elements are then released back into space, contributing to the formation of new stars, planets, and life.

Was the Orion nebula a nova or a supernova?

The Orion Nebula was not formed from a single supernova or nova event. It is a stellar nursery where new stars are currently being formed. The nebula is created by the glowing gas and dust illuminated by newly formed stars within it.


What is the differences between super nova and neutron star?

A supernova is when a massive star explodes. A neutron star is what can be formed after a supernova explosion. See related questions


How are elements heavier than iron are formed?

Elements heavier than iron are formed in super-nova explosions.


What occurs before a supernova explosion?

Nuclear fusion stops and the star is no longer capable of transformming LIGHTER elements into HEAVIER. elements. At this point GRAVITY looses out and PRESSURE wins out thereby causing the supernova explosion. But bear in mind, there is a HUGE difference between an ordinary star going NOVA and a SUPERNOVA.

Why do stars explod and why?

Yes, they do. This is called a nova or supernova, depending on its mass. The supernova outshines every star you can see usually depending on the distance. If a star is big enough, the supernova can create a black hole in space. The crab nebula was formed by a supernovas about 1,000 years ago.

An explosion of a star?

When a star explodes, it releases an immense amount of energy, creating a supernova. This explosion can outshine an entire galaxy for a short period of time. Supernovae are crucial for the formation of heavy elements and can also cause the star to collapse and form a black hole or neutron star.
