S Process Since A Star's H
2,723 wordsThe "big bang" which created the universe, only created the elements Hydrogen (H) and Helium (He) and possibly a very small amount of Lithium (Li). However, a glance at the periodic table of the elements shows that today (some 15 billion years after the big bang) there are at least 108 known elements. Every atom of every element heavier than Li has been produced since the big bang! The "factories" which make these elements are stars. "Nucleosynthesis" or the synthesis of nuclei, is the process b...

Helium Core Fuses Into Carbon
1,937 wordsFusion For centuries, humankind has looked at the stars, and for just as many years humankind has tried to explain the existence of those very same stars. Were they holes in an enormous canvas that covered the earth? Were they fire-flies that could only be seen when the Apollo had parked his chariot for the night? There seemed to be as many explanations for the stars as there were stars themselves. Then one day an individual named Galileo Galilei made an astounding discovery: the stars were repl...

Research On Stars And Black Holes
1,178 wordsBy Beatrice A. Lopez Below you will read research on stars and black holes. Black holes are stars whose core has been crushed by gravity. In the text to follow you will see how a star forms, read about its life and how it becomes a black hole. Stars are composed of hydrogen gas and dust. Stars owe their existence to the force of gravity. Stars are created from the thinly spread atoms of dust and gas that swirl throughout space. The atoms clump together into dense clouds that eventually collapse ...

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...

Stars In The Clusters
446 wordsBlue Stragglers Scientists have recently found that odd stars known, as "blue stragglers" may be the product of collision between two, and possibly more, older stars. This may result in finding out a 50 year-old mystery of the blue stragglers. Even in "dense" areas stars a typically billions, if not, trillions, of miles apart. But stars may have the occasional chance to collide in global clusters, which are dense groupings of up to a million stars wit tightly packed cores. Some global clusters a...

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...

Lower Main Sequence Star
1,225 wordsStars over Time star is a self-luminous ball of gas bound by gravity into a single object and powered by nuclear fusion at the core. There are trillions and trillions of stars in our universe and all are different and unique. There are many stages of stars life including main sequence stars, red giants, white dwarfs, neutron stars, and black holes. All stars also have many more variations in each stage of life. The life of a star begins in a nebula, a great collection of gas and dust. Once enoug...

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...
