Stars With Initial Masses
1,224 wordsHuman life is a very beautiful experience. The process starts with the fertilization of the egg, to the birth of a baby, through the life a person up until the death of that person. The life cycle of a star is a process that is just as beautiful and fascinating. Before the star begins its life, there are the components that will create the star. The components look as little like the star, then the sperm and the egg look like a baby. However, unlike the creation and life cycle of a human, the ul...

Blue Class B Hadar
831 wordsHadar, also known as Beta Centauri, is the 10th brightest stars (11th as viewed from Earth). Hadar is a blue-white super giant in the constellation Centaurus (Cen). In about 4,000 years, the motion of Alpha Centauri, who's proper name is Rigel Kentaurus, will carry it close enough to Hadar that they will appear to be a magnificent double star. Because of the distance away from Earth that Alpha and Beta Centauri are (approximately 90 parsecs), they will be an optical double. As they sit today, th...

Mass Of The Nebulae
546 wordsPurpose: to become familiar with the image analysis program and to develop an understanding to the size and age of planetary nebulaeProcedureThe first part of the experiment involved using a picture of a church and back round to understand different pixels, ADU, zoom, and how to get the (x, y) coordinates. We then took this brief understanding of pictures and applied it to the stars. We loaded a picture of nebulae m 42. After this we needed to calculate the average number of stars or solar masse...

Main Sequence Stars Of Different Masses
2,673 wordsLIFE CYCLE OF A STAR Stars are formed in nebulae, interstellar clouds of dust and gas (mostly hydrogen). These stellar nurseries are abundant in the arms of spiral galaxies. In these stellar nurseries, dense parts of these clouds undergo gravitational collapse and compress to form a rotating gas globule. The globule is cooled by emitting radio waves and infrared radiation. It is compressed by gravitational forces and also by shock waves of pressure from supernova or the hot gas released from nea...

High Mass Stars
682 wordsThe Life of a Star One night while little Jimmy was out camping with his father, he asked his father how a star is made? And his father said there are high-mass stars, intermediate-mass stars, and low-mass stars. The life cycles of stars follow three general patterns each associated with a range of initial mass. Much like human beings stars have a life cycle, they go threw birth, evolution, and death. And little Jimmy said how is that possible? First the star must be born. Many astronomers belie...

Origins The Origins Of White Dwarf Stars
2,780 wordsAlthough they are tiny in size, white dwarfs have played a great role in astronomy. These compact stars are very different from familiar objects like our sun. They also pose a seemingly endless series of puzzles, whose solutions provide new insights into many areas of physics and astronomy. To unravel a wide variety of phenomena such as cataclysmic variables (novae, dwarf novae), planetary nebulae, and some types of supernova, we have to understand white dwarfs. These stars may even hold clues t...

Mass At The Center Of The Star
1,220 wordsThe night sky, unimaginably deep, is a breathtaking sight. Some three thousand stars can be seen with the naked eye, twinkling points of light that have inspired the human spirit since the dawn of time. Study of the stars, based on data collected from visible-light telescopes, radio telescopes, and detectors wavelengths can now reveal extraordinary amounts of information: size, temperature, chemical composition, internal structure, distance and rotation rate, among other factors. One of the most...

Collapse Of The Neutrons Star
584 wordsBlack holes by supernova Firstly, a black hole isn't really a hole at all, but that's the easiest way to think of its effects on the rest of the universe. Take a star that's at least thirty times larger than our sun and make it explode (called a supernova). Stars do that at the end of their lifetime, sometimes leaving a remnant of the violent explosion. The nature of the remnant depends on its mass. If the remnant is less than 1.4 solar masses, it will become a white dwarf, a kind of hot dead st...

Type II Supernova Explosion
746 wordsA supernova is a STAR that explodes. It suddenly increases in brightness by a factor of many billions, and within a few weeks it slowly fades. In terms of the human lifespan, such explosions are rare occurrences. In our Milky Way galaxy, for example, a supernova may be observed every few hundred years. Three such explosions are recorded in history: in 1054, in 1572, and in 1604. The CRAB NEBULA consists of material ejected by the supernova of 1054. Such materials, known as supernova remnants, ar...

Star Collapses To Singularity And A Blackhole
628 wordsThe term blackhole is misleading, as they are not holes, but heavy, dense stellar bodies. The more dense, and massive an object, the more it warps the fabric of space-time, creating ever deepening gravity wells. These gravity wells draw in other stellar bodies, adding their mass to that of the blackhole, increasing it's gravity, and the size of what is called the event horizon. The event horizon is the distance from the singularity that the gravitational effects weaken to the point where light c...

Apparent Magnitude A Star
794 words1. a) What is a constellation? A constellation is a group of stars that appears to form a pattern in the sky. b) What are circumpolar constellations? Give examples. They appear to move around Polaris the star located almost exactly above Earth's North Pole. Ursa Major, Ursa Minor and Cassiopeia are examples of circumpolar constellations. c) Describe and explain the apparent motions of the stars in our sky? The apparent movement of circumpolar constellations is caused by earth turning on its axis...
