Formation Of Stars Research Paper

Stellar evolution stars exist because of gravity. The two opposing forces in a star are gravity (contracts) and thermal nuclear energy (expands). Stage 1 Birth is where gravity contracts the cloud and the temperature rises, becoming a protostar. Protostars are a hypothetical cloud of dust and atoms in space which are believed to develop into a star. Astronomers are fairly certain of their existence. Protostars are formed about a million years after a gas clump from an interstellar gas cloud has started

In this paper I will explain how astronomers determine the composition, temperature, speed, and rotation rate of distant objects using various methods. I will explain the properties of stars. I will also summarize the complete lifecycle of the Sun and determine where the Sun is currently in its lifecycle.

The Low mass stars spend there main life as a fusion machine which turns hydrogen into helium and a very slow and methodical pace. When the energy released by this fusion reaches the surface it is released into space and this is the star luminosity. Over a long, long time sometimes billions of years a low mass star consumes the hydrogen in its core and converts it to helium, at which point the core starts to contract and shrink. Once all of the hydrogen inside the stars core begins to become totally exhausted, the core pressure gives way to the crush of gravity because it has no more fusion occurring in its core at that time. As the core shrinks rapidly and the outer layers start to expand the stars shape begins to grow in size and its luminosity becomes extraordinary brighter due to the outer shell starting to produce fusion more rapidly then the core did during the main sequence life of the star. As this situation grows more rapidly and extreme the core starts to rapidly burn again and fuse its core helium into carbon. Then just before its final death the star ejects its outer layers into space. This leaves only the degenerate carbon core and since this core is still very hot it emits intensely powerful ultraviolet radiation and glows brightly in what is known as a planetary nebula. The nebula fades and cools over around a million or so years and we are left with a white dwarf cooling indefinitely till

TOPIC SENTENCE NEEDED. These stars are the mass of the sun squished down to the size of a city. They meausure 20 kilometer or 12.5 miles across. One sugar cube of a Neutron star weighs about 1 trillion or 1 billions tons. There is another type of neutron star called a magnetar. The magnetic field of a neutron star is trillions times stronger than the magnetic field. A magnetars magnetic field is 1000 times stronger. Their known to erupt with no warning.

The life cycle of the star is a long process that has taken place for billions of years and will continue to take place long after our star is no longer in existence. In this essay I will be explaining the magnificent process of how a star is first born till the end of its life cycle. First, I will be explaining how the star is first formed in all its beauty big or small. Then, I will be explaining the path of an average star like our own sun will take. After, I will be explaining the journey of a massive star in all its glory till its destructive end. All stars are first formed in clouds of gas called nebulae, turbulence deep within the nebulae causes cores to form as the mass begins to grow the nebulae begins to collapse upon itself due to

When we think of stars, we often think that they are all the same. We often think that they are all just big balls of gas burning up to billions of light years away. However, that isn't exactly true. The truth is that stars are very diverse. Just like anything else in our Universe, stars fall into many different classifications based on its defining characteristics. In this essay I will discuss several different types of stars.

This star is formed after a large star has had a supernova explosion. These stars are usually very dense and will eventually produce a black hole. Magnetar is a neutron star with an extremely strong magnetic field. Magnetar stars are highly magnetic objects, they are even stronger than Earth. It is also 100 to 1,000 times stronger than radio pulsar. Because we are unsure how this star can be as strong as it is, theorist say it would have to rotate between 100 to 1,000 times per second. Brown Dwarfs is the in between size of a giant planet and a large star. This star is also a very dense star, but not as dense as the white dwarf. When a star is dying it squeezes all its matter into a tiny space, this is called a Black Hole. Their gravity is so strong from all the matter in a tiny space that nothing, not even light can escape. You can’t detect a Black Hole with the naked eye because it's actually invisible, you need a science telescope to identify them. The Cepheid Variable stars light brightens and dims many times. It’s like when the sun is out then goes behind a cloud then comes back out

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.

Those stars in the night sky seem small and tiny, but up close they would be millions of times larger than the Earth. Stars are the most recognized astronomical objects and are the building blocks of the galaxies. These luminous spheres made of plasma are responsible for the creation of heavy elements like carbon, nitrogen, and oxygen. They were among the first objects in the early universe. Most of the elements found in the human body originated in stars, this means that we are literally made of stardust. When you are staring at stars from the night sky, you are actually looking back in time, the light you see could be from a million years ago. The study of the birth, life and death of stars are the central field of astronomy today.

These celestial bodies begin as a region of cold, high density nebula that condenses into a globule of gas and dust. Over millions of years, the cloud is compacted and the cold nebula gas begins to heat up as the molecules get excited for reacting together. Atoms within the nucleus of this Protostar begin to clash with one another combining hydrogen atoms to form helium atoms. As a result, the energy needed to sustain itself throughout its life, is created by these reactions within the transformation

Before a star is born, massive clouds of dust and gas are pulled together by gravity in space, called a stellar nebula. These massive clouds are pulled to the center of the collapse into a number of points, or course within them. In the middle of the core, several events

They are scattered throughout the galaxies. A stellar black hole is the product of the death of a giant star such as a pulsar or a neutron star. Black holes in general are very rare because most stars are not massive enough to create them. When a star stops producing fusion energy, the equilibrium of the star no longer exists. Without the star producing any fuel, there is no pressure created that can hold the star in place. The pressure that a star creates is used to prevent the gravity from crushing the core. Now that there is no pressure pushing outward, the gravity becomes so violent that it crushes matter to the point that it is completely destroyed. At this point, black holes are born. Black holes are created in rare occasions. During the death of most stars, they slowly dim out or explode into trillions of microscopic particles. For example, the sun, which is a red dwarf, will slowly die out. Eta Carinae on the other hand, located 8,000 light years away from Earth, is likely to explode within the next several hundred thousand

Similar to white dwarfs, neutron stars formed when the original star cannot support themselves against gravitational collapse by generating thermal pressure. They are born from once large stars that grew to be four to eight times the size of our sun before exploding. After the explosion, the only part of the star that remains is its core, but it no longer produces nuclear fusion. The neutron star density causes protons and elections to combine into neutrons, which is how the star got its name. Neutron stars rotate in space when they are formed but as they compress and shrink, the speed of rotation increases. A form of neutron stars are called pulsars. Most neutron stars gradually slow down over time, but the ones that remain spinning emit radiation that cause the star to appear

The central part (the 'core') of the star undergoing 'supernova' explosion, collapses into a neutron star of mass in the range of 1.1 – 2 solar masses. During the collapse, atoms of the progenitor stars break, and subatomic particles become free and then positively charged protons convert to charge neutral neutrons (in addition to already existing neutrons) by adsorbing negatively charged electrons. Neutron stars are very dense objects. Their density can be as high as 1014 gm per cubic centimetre. They are also highly magnetised, their magnetic fields are usually in the range of 108 to 1016 Gauss (the strength of refrigerator magnets is around 50 Gauss). Neutron stars also spin very fast, rotating up to a few hundred times in a

Indecent bodies like the sun. Stars are made up of big exploding balls of gas, mostly hydrogen and helium. The sun is similarly a star made up of huge amounts of hydrogen, undergoing a continuous nuclear reaction like a hydrogen bomb. Stars come about when vast clouds of hydrogen, helium and dust contract and collapse due to gravity. The clouds came from astronomical plasma from “The Big Bang”, but the dust comes from the supernovae of other stars.
