 How stars die - the death of stars in English

1. death of stars in English - You must know that whatever things we are seeing in the universe,
2. Like a star, a galaxy, or whatever, they are bound to come to an end one day.
3. These comets, meteors, galaxies, all these will be destroyed one day.
4. In the same way, the stars that twinkle in the sky will also be destroyed one day.
5. And the process of the death of stars is very interesting and exciting.

So let's know how a star dies after all…..

    

The death of stars depends on their mass:

The death of stars depends on the mass of the stars.

The more mass a star has, the more material it has.

But due to the gravitational force of a high-mass star, the temperature of its core is high.

Therefore, the material of that star gets burnt quickly. And they die sooner than stars with less mass. (death of stars in English)

For example, a Red Dwarf star which is only about 50% of the mass of its Sun,

It is one of the longest living things in the universe.

A Red Dwarf Star Due to its very low mass and low core temperature

It Burns its material very slowly. And these flashes are also very few.

How do stars of different masses die?

Now from here, we talk about how stars of different masses die.

Let me tell you this thing that a low mass star dies in a different way,

A medium mass star dies differently, and a large mass star dies differently.

Death of a low mass star: white dwarf

The stars which are from 0.08 to 8 times the mass of the Sun are considered to be low mass stars.

When these low mass stars fuse their entire material.

So the process of nuclear fusion in them stops.

Due to which the outward force due to the nuclear power of the star

And the inward force which is due to the gravitational force,

Unable to stay in balance. And the star leaves 50% of its mass outside in the form of a planetary nebula.

And only the bright bright core of the star remains, which is called a white dwarf. (death of stars in English)

After shining for billions of years, these white dwarfs are finally destroyed as black dwarfs.

Death of a medium mass star: A neutron star

Medium mass stars are 8 to 20 times as massive as the Sun.

After the fusion stops in these stars when the mass of the core of these stars reaches 1.4 times the mass of the Sun,

Then the electron and proton react inside the molecule of its core to form a dense core of neutron.

And the layer outside the core spreads out into space due to the supernova explosion.

and leaves behind a very dense sphere of diameter about 25 km,

This sphere becomes the neutron star. These neutron stars die after losing energy for billions of years.

Death of a star with more mass: Blackhole

High-mass stars that are 20 times or more massive than the Sun.

When these stars are at their end, their cores continuously shrink inside themselves to form black holes (death of stars in English).

In this, when the core of the big star becomes 1.4 times the mass of the Sun,

Then these stars make a black hole by continuously shrinking due to their gravity along with the supernova explosion.
