Formation Of A Dying Star Essay

According to Carolyn Ruth, author of “Where Do Chemical Elements Come From,” chemical elements came from the explosion of stars, also known as supernovas. In her article, Carolyn states that a newborn star is mainly composed of the first element on the periodic table, Hydrogen. Due to the high pressure within the star, a fusion process begins that fuses two protons and two neutrons together to form the second element, Helium. These fusion processes continue to form elements that weigh less than Iron. Once the star creates all elements up to Iron, the star eventually collapses and explodes. One article that agrees with Carolyn’s theory is “The Origin of the Elements and the Life of A Star”. According to this article, stars produce nuclear reactions

Although Stardust was created from Hydrogen, and most of the universe is Hydrogen, one must remember that our planet, our race, and ourselves were created from the other elements that arose afterwards in stars. So one could conclude that just as we were made from Stardust; Stars were made from Big Bang dust. We are connected to the objects created a bit after the origin of existence. A very majestic truth in

What happens to a star during the rest of its life depends of how massive

Stars are born of gas and dust and have a life cycle based on their original mass. Stars are not alive, but they go through stages. There are many sources that prove that this fact is true! These sources include the life cycle of stars, star classification, and types of galaxies. These different life cycles are for the high-mass stars and the low-mass stars.

A star has 5 definite stages and 3 stages which can vary between stars. The 5 definite stages are a Nebula, a Star, a Red Giant, a White Dwarf and a Red Dwarf. The stages that can vary are a Supernova, a Neutron Star and a Black hole. As the star goes through each stage, it can change size dramastically. An example of this is a Red Giant, which is 100 time the size of the Sun, compared to a Red dwarf, only 1 tenth the size of the sun (Life cycle). An interesting fact is “The closest star to Earth is Proxima Centauri, located 4.2 light-years away. In other words, it takes light itself more than 4 years to complete the journey from Earth. If you tried to hitch a ride on the fastest spacecraft ever launched from Earth, it would still take you more than 70 000 years to get there from here.” (Interesting facts)

Then, overtime the giants gasses drift away from the core then the gasses appear as a cloud around a dying sunlike star. When the clouds disperse, gravity causes the remaining matter in the core to collapse inward. The core becomes denser and very hot, then the star becomes a white dwarf. A white dwarf is the hot, dense core of matter that remains from the collapse of a low mass

After a star lives for about 1 million years, it becomes a main sequence star. Once it becomes a main sequence star, it will then go through a proton-proton chain reaction. Since the force of gravity goes inward, the force of fusion will then go outward from the core. This process will continue for about 10 billion years even when the star is "burning" Over those ten years, the stars will eventually slowly run out of hydrogen. After it runs out of hydrogen, the core will fill up with helium.

The first process every star goes through before its end is the process of their core shrinking. When stars of at least .4 M begin to exhaust their hydrogen supply, the hydrogen starts to fuse in a shell that is outside the helium core. As the shell burns more hydrogen it is also producing more helium, this allows the core to increase in its mass and temperature. When the temperature increases greatly, helium fusion begins to start in what is called a helium flash, causing the star to rapidly decrease in its size and increase its temperature. Once the star has fused all of the helium out of its core, the product of the carbon will fuse which produces a hot core along with the outer shell made up of fusing helium. The more massive a star is,

We know of many stars that exist, but the main stars are White dwarfs, Pulsars, Neutron stars, Magnetars, Brown dwarfs, Black Holes, Cepheid Variable stars, Supergiants, Red Giants, Novas, and Quasars. Starting with White Dwarf, this star is usually the size of a planet and is last stage of a stars life, when it loses all its layers from the planetary nebula. This star is very dense and especially hot after it disables its nuclear fuel. It starts to cool done over the next billions of years. Pulsars, this star is practically a white dwarf star, but has electromagic ration beaming out of it. There are two steady lights (electromagic ration) that point in two opposite directions. It always seems to be blinking, but this is just from the motion

Remember the phrase “We are all star stuff”, we’ll it’s true. The matter and elements our bodies contain were made from a detonating star, which has additionally given us distinctive numbers planets and different stars. The blast of a star is known as a supernova (supernovae for plural employments). Supernovas are extremely intriguing, brilliant, and vital, for a hefty portion of reasons, however to start with, you'll need to comprehend what a supernova is.

A blindingly bright star bursts into view in a corner of the night sky — it wasn't there just a few hours ago, but now it burns like a beacon. That bright star isn't actually a star, the brilliant point of light is the explosion of a star that has reached the end of its life, otherwise known as a supernova.

In most cases a star will move into the planetary nebula phase, as an expanding, glowing shell of hot gas also known as plasma. This happens from a low-mass star in the end of their red giant phase, becoming unstable. The exterior layer drifts away from it’s core, which is now consider a white dwarf star, due to stellar winds. If the dying star have a mass of over 8 suns, it will become a supernova. Just like a planetary nebula, the cause of it is when a star runs out of nuclear fuel. From the massive star’s lack of outward pressure to balance its inward gravity, the star collapses into the core expelling a nuclear explosion. Also like the nebula, gas and dusts are scattered around space that will be used for the birth of future stars. At this point, the former supergiant is either a neutron star or a black

Supernovas are the explosion of a star when it reaches the end of its life. There are two ways a star can go supernova. The first way or a Type I supernova occurs in the Binary system which is when two stars orbit the same point. The two stars are a white dwarf and a red giant. A white dwarf is a small dense star that is around the size of a planet and a red giant is a star at its last stages of life. If these two stars are close enough, matter will be transferred to the white dwarf from the red giant. When the star’s core reaches its limit of matter, a thermonuclear detonation will occur leaving nothing behind unless there were leftover elements in the white dwarf or there were elements made in the supernova explosion. One of the elements made in the explosion is radioactive nickel.

When giant stars die in supernova and their core collapse that is when a neutron star is created.This neutron star is several times bigger than the sun.Because the neutrons are tightly put together into a super dense object the supernova is very heavy it weighs about 100 million tons.

Main sequence stars like our own sun enduring in a state of nuclear fusion during which they will produce energy for billions of years by replacing hydrogen to helium. Stars change over billions of years. When their main sequence phase ends they pass through other states of existence according to their size and other characteristics. The larger a star's mass, the shorter its lifespan is. As stars move toward the end of their lives, much of their hydrogen will be converted to helium. Helium sinks to the star's core and raises the star's temperature—causing its outer shell to expand. These large, puffy stars are known as Red Giants. The red giant phase is actually a prelude to a star shedding its outer layers and becoming a small, dense body called a White Dwarf. White dwarfs cool down for billions and billions of years, until they finally go dark and produce no energy at all. Once this happens, scientists have yet to observe, such stars become known as Black Dwarfs. A few stars avoid this evolutionary path and instead go out with a bang, exploding as Supernovae. These violent explosions leave behind a small core that will then turn into something called a Neutron Star or even, if the remainder is large enough, it is then turned into something called a Black Hole.
