A Star is Born Stages in the Stellar Cycle - 550 Words

A Star is Born: Stages in the Stellar Cycle (Essay Sample) Content: A Star is Born: Stages in the Stellar Cycle David Moadel December 19, 2011 A Star is Born: Stages in the Stellar Cycle   Astronomy is often thought of as a source of fascination for scientists and other sky-gazing intellectuals. However, the heavenly bodies in our skies should not only interest the privileged few. Consider, for example, the life cycle of a star. Stars, like living organisms, experience an inevitable sequence of stages. Throughout the phases of nebula, collapse, proto-star, and main sequence star, the stellar cycle can hold great interest for even the most casual observer. Any star, large or small, begins as a nebula, or a cloud of dust composed primarily of hydrogen and helium (ASPIRE Lab, 2010b). The nebula may be thought of as the nursery out of which a star emerges. Through a natural process known to scientists as accretion, the nebula gathers mass into clumps, and as the clumps get bigger, the nebula's gravitational pull increases. This, in turn, causes more mass to be pulled into the nebula. Over time, the star forms when enough matter clumps together to reach a critical mass of approximately 80 times the size of Jupiter (Stellar Birth, 2006). At this point, the internal pressure of the mass rises to an extraordinary degree -- high enough, in fact, to ignite nuclear fusion. As intense as this may seem, it is merely the beginning. The next phase of a star's life cycle is the collapse of the nebula. With its incredibly high temperatures, the hydrogen atoms in the newly formed star begin to fuse together (The Birth of a Star, n.d.). This proves to be a good news-bad news situation. The good news is that light and heat, giving rise to the star's "shine," are emitted. The bad news is that the star's mass becomes greater than it can bear, and it collapses. Can this poor star recover from its near-death experience? To discover the answer, we must explore the next ph ase: the proto-star. Perhaps the most exciting phase of the stellar cycle, the proto-star phase entails the rebirth and rebuilding of the star. In this phase, clumps of gas and dust group together in the nebula, and by this stage, the gas is sufficiently dense that it does not lose heat (Stellar Birth, 2006). This process typically requires hundreds of thousands of years, and eventually we end up with a giant clump of matter called a proto-star. Thus, the center of the former nebula shrinks as it heats up, essentially creating a new star (The Star Cycle, n.d.). To borrow a Hollywood clichà ©, star is born -- or, more accurately, reborn. At this point, the star enters into the phase known as the main sequence, where it lives out the majority of its life (ASPIRE Lab, 2010a). This stage of the stellar cycle is comparable to adulthood in humans. As you may have surmised, our sun is a main sequence star. This type of star shines light into space for billions of years, losing e nergy in the process. In addition, a main sequence star gradually contracts, or pulls inward, due to the strong gravitational force at its core. Sadly, all good things must come to an end. Stars do not last forever, as their fuel will be used up sooner or later (Star Death, n.d.). Most stars, including our own sun, will convert their hydrogen to helium over many years through nuc...

The Differences between Command Economies and Free Market...

The Differences between Command Economies and Free Market Economies The prime difference between command economies and free market economies is the method used to answer the three central questions of what, for whom, and how? Each of these questions relates to production. In a free market economy, the answers to these questions are decided by the consumer and overseen by a government that practices a laissez-faire economic policy. Production is decided on a supply and demand basis- resulting in a capitalist society. This happens due to the dispersion of wealth throughout an economy, the richest dictating which products should be produced due to their own demands, and the poorest having little†¦show more content†¦This type of economy works in the private sector of business ie. Individual firms. A command economy is an entirely different system in which a central government decides how to answer the three central economic questions. The government would decide what is to be produced, how it is to be priced etc. resulting in a far more communist state. This obviously gives the government a far more autocratic role in their economic policy in contrast to the free market economy. Products are designed with the incentive to meet consumer needs rather than to meet the wants of the richest. This way is far more practical towards ensureing the production of necessary goods. This type of economy works under the public sector- everything is funded and controlled by the central government. Discuss Whether there are Lessons to be Learned Between the Two Systems No economic system will ever work flawlessly so it is undoubtable that these two systems would be able to adapt to become more practical. For one example, in the free market economy, there have often been problems with failure to produce medicines that are seen bt medical companies to be unprofitable but that are ncessary to public health.

The lights dimmed, the crowd roared, the piano boomed and the show began it was Billy Joel, live at Madison Square Garden. It had been four years since I had seen Joel on tour with Elton John and I was hoping his alcoholism had not affected his music. When the show started, all my doubts were put to rest. Starting with â€Å"Angry Young Man,† Joel showed he still has incredible talent. Accompanying Joel was his band, almost all from the New York metropolitan area. After â€Å"Angry Young Man,† he began the set list with songs from early albums, â€Å"The Nylon Curtain† and â€Å"52 Street.† It was nice to hear songs like â€Å"Zanzibar† and â€Å"Stiletto,† plus some I didnt know and others I had not heard in years.

Writing a Critique Journal Article

Writing a Critique Journal ArticleIn this article, I want to give you three tips for writing a critique journal article. You don't have to write your critique, but it is extremely helpful to write a critique of your own research and then have a mentor read your critique and tell you if it will pass their standards.Jokingly, this is called being too nice. In writing a critique, you are being kind. This means that when your mentor reads your critique, they will know what you mean when you say 'Yeah'I disagree.'Jacques-Louis Cailpot-Beaubien explained it to me as being similar to telling your child 'You're right, Mom!' In this analogy, the mentor knows more than you do. The mentor can judge whether or not your critique is based on sound scholarship. You can't judge the value of your critique because you haven't read the same work. In any case, this doesn't mean that the mentor is right; it means that your critique isn't as good as the critique of someone else.And in critiquing your own work, don't be too defensive; instead, come off as a master of your field. Make yourself look good by saying that what you wrote was a revision of a previous work. If you have a student do a critique for you, have them rewrite your article, and then revise it so that it reflects their work.Never try to circumvent your reader. The reader will infer that you're hiding something, and that's not how to engage the reader.Remember that the reader will read your critique more than once. They will read your critiques from one student to the next, and even if you've written more than one critique, have a student read it again from the first time. That way, they can get a sense of the difference between your first and second critique and can compare them to see which one stands out the most.And finally, critique your work for a dissertation committees. You can find some of them online and submit them online. But again, use your judgment as to whether you want to become involved with dissertat ion committees.Remember, if you follow these three suggestions, you should be able to write a critique in less than twenty-four hours, Jacques-Louis Cailpot-Beaubien. Enjoy!
