Astronomers have given the basic glimpse of a dying star – confirmed the ideas of making nuclear

Astronomers have shown a glimpse of the inner structure of the dying star in a rare type of cosmic blast called “extremely stripped supernova”.

In an article published today NatureSteve Shloos and colleagues of North Western University in the United States have described a fat shell of Supernova 2021yfj and its surrounding gas.

Their searches support our current ideas about what happens within the end of their lives within the stars.

How do stars make elements

The stars run through nuclear fusion. This is a process in which light atoms work together to release heavy energy.

The fusion star is in the stages of life. In a series of bicycles, the first hydrogen (the lightest factor) is found in the helium, followed by heavy elements like carbon. The largest stars continue to be neon, oxygen, silicon and finally iron.

Every burning cycle is faster than the previous cycle. The hydrogen cycle can continue for millions of years, while the silicon cycle has ended in a few days.

Since the main part of the mass stars continues to burn, gas out of the core obtains a layered structure, where the other layers record the development of the burning cycles.

While all this is running in the basic part of the star, the star is also pouring gas from its surface, it has been taken into space by wandering air. Each fusion makes a spreading shell of cycle gas, which has a different mixture of elements.

The basic elimination

What happens to a massive star when the main part of it is full of iron? Heavy pressure and temperature will make iron fuses, but unlike the fusion of light elements, this process absorbs energy rather than releasing it.

The release of energy from fusion is the one that maintains the star against the power of gravity – so now the iron core will fall. Depending on how big it is to start, the falling core will become a neutron star or a black hole.

The process of falling produces a “bounce”, which flies out of energy and material. This is called the Core Claps Supernova blast.

Before the explosion, the layers of gas excuses are illuminated, which allows us to see what they are made of. So far, in all the famous Supernova, the material was either hydrogen, helium or carbon layer, which was first manufactured in two nuclear -burning cycles.

The inner layers (neon, oxygen and silicon layers) are ready just a few hundred years before the burst of the star, which means they do not have time to travel away from the stars.

An explosive mystery

But this is something that makes the new supernova SN2021yfj so interesting. Shloos and colleagues found the material outside the stars, the silicon layer, which is the last layer of iron cover, which is made on a few months’ time scale.

Before the explosion took place, the wind would have removed all the layers from the silicon completely. Astronomers do not understand how powerful the wind can be so powerful that they do.

The most understandable scene is that the second star was involved. If another star was wandering one of the bursting, his gravity may have pulled the deep silicon layer quickly.

The bursting stars have done the universe today

Whatever the explanation, this theory within this star has confirmed our views of nuclear fusion within large -scale stars.

Why is this important? Because the stars are the place where all the elements come.

Carbon and nitrogen are mainly manufactured by lower -scale stars, which are like our own sun. Some heavy elements such as gold collision and integration neutrons are manufactured in a foreign environment to connect stars.

However, oxygen and other elements such as neon, magnesium and sulfur come mainly from the Core Collips Supernova.

We are because of the internal work of the stars. The permanent production of elements in the stars causes the universe to constantly change. Later -made stars and planets are very different from those formed in the past.

When the universe was small, it was very few in the way of the “interesting” elements. Everything worked in a different way: the stars burned and burned and the planets could not be less, different, or at all.

How much supernova burst and what she has brought out in the Intestile Space is an important question to know why our universe and our world are.
