Average and massive star formation

Stars varieties in a very dense region of Nebula (Orion Nebulae) and scattered throughout most galaxies. Stars are born if a group of atmosphere and dust (Cepheus B) start to collapse below its own the law of gravity.
Because the cloud collapse, the materials in the centre begin to heat up and the particles (clouds and dust) start to fuse together which can be the energy way to obtain the stars. Therefore , the star starts to glow forming Protostars. Protostar may be the hot main at the heart of the collapsing cloud that will be a star. The central temperatures of a protostar is able to reach 15 million degree Celsius when their contain matters enough.
During the high temperature, hydrogen atoms of new created star combines together to form helium (diffusion) which creates energy that powers the star.
The stars start to release energy, preventing the star via collapsing and causes it to shine, being a Main Pattern Star including Sun.
The photo voltaic mass of any star is still the same in main sequence for about 15 billion years, until each of the hydrogen has become used up and fused with each other, forming helium about 60 million years and became mature from the beginning of the collapse to adulthood. The Sun will certainly stays in mature phase for about 15 billion years.
The helium core begins to fall further and the star become denser and hotter.
When helium core is hot enough, the helium begins to contact form carbon and oxygen. Because the celebrity begins to fuse helium, it creates more strength, causing the outer layer from the stars to expand. Some day, our Sun will expand very large that may swallow up each of the planet in the solar system but it will surely become a Crimson Giant.
The helium core deteriorate, and the exterior layer with the star gets further from the center and force of the gravity will obtaining weaker, causes the outer tiers leaving away from the core and expand to be able to become a Planetary Nebula (the most beautiful items in the universe).
Stage on the lookout for
The remaining core becomes a White Little which is only about the size of the entire world that is incredibly dense and hot. Following millions of years, it will cool-down and become a Black Dwarf.
A lot of the massive stars live intended for billions of years.
More than the Sun (9 times).
Massive superstars gets fully developed from a small stars until it actually reaches its primary sequence superstar which the method is similar to the growth of normal star (from stage 1-4). The stars stand out steadily before the hydrogen offers fused, developing helium which takes an incredible number of years.
The massive superstar becomes a Reddish colored Supergiant and the helium main surrounded by a layer of expanding smells.
In the following million years, different elements in shells about the iron main are shaped by a series of nuclear reactions.
Once enough hydrogen has accrued on the area, nuclear blend occurs, causing the white colored dwarf to shine brightly and release the remaining elements. Within a couple of days, the light subsides plus the cycle begins again. Occasionally, some large white dwarfs may accrete a large mass of factors which creating it to break down and explode completely, becomes a Supernova.
When a legend explodes as a supernova, the majority of its elements is released away into space to form a nebula. The high heavy remnants from the imploding core which are left behind are termed as a neutron star, as its electrons and protons are smashed together inside the huge gravity to form neutrons. Chandrasekhar limit (Subrahmanyan Chandrasekhar, 1935) had been established which can be about 1 . 5 sun masses previously mentioned which a star need to continue to break under its gravity into a neutron star. However , in case the core in the star is definitely greater than a few solar people, the key collapse and can become a Dark Hole.
