continuously learning new things. One area that amazes scientists is magnetars and pulsars. This report will discuss the formation of these stars‚ their characteristics‚ and the effects they have. Magnetars and pulsars are formed from the remnants of a Type II supernova 1. The exploding star is typically bigger than the sun 2. Having a mass greater than 1.989 X 10^30 kg 3.The star often dies because they no longer have the light force pushing outwards which counter acts the massive gravitational force (1 of

Close reading and response to literature Number The Stars -Lois Lowry 1. What are the major themes of this book ? Difficulty of growing up The author Lois Lowry uses the context of World War II as a way of making the difficulties stand out more clearly. The novel focuses on Annemarie Johansen’s personal experiences with growing up‚ but her experiences are common to most young people. Growing up is presented as a struggle for identity. Does Annemarie belong to the world of adults or

The Life of High Mass Stars High mass stars can be classified as any star that is at least four times the solar mass of our star‚ the sun. They consist of about three percent of all of the stars in the universe‚ but there are still billions and billions of them all over the universe. High mass stars‚ like low mass stars‚ begin to form from clouds of gas and dust in space. They both begin as a protostar and eventually become dense enough to cause hydrogen fusion within them; placing them both on

Term paper outline-Death of stars http://www.space.com/6638-supernova.html http://en.wikipedia.org/wiki/Stellar_evolution Abstract (summar of paper) When observing a star‚ the lager it is the shorter its life is going to be. The smaller it is the longer the life. Shorter life is not saying much though‚ as the most massive stars live for billions of years. When a star reaches about middle age‚ it starts fusing hydrogen into helium. Once it has run out of usable hydrogen that it can convert

Before a star even becomes a star‚ scientists are tracking its every move and every phase it goes through. Scientists do this for high mass and low mass stars because they both go through similar life cycles. The difference? A high mass star burns out in just a few million years while a low mass star could take almost ten billion years to burn out. HIgh mass stars develop much quicker because of their massive core‚ which is how they get their name. A high mass star will start growing in a nebula

The Stellar Lives of Stars Stars are giant nuclear reactors. In the center of stars‚ atoms are taken apart by tremendous atomic collisions altering the atomic structure and releasing an enormous amount of energy that makes stars hot and bright. Nuclear fusion is an atomic reaction that fuels stars. In fusion‚ many nuclei combine together to make a larger but different element‚ and the result of this process is the release of a lot of energy. Stars are powered by nuclear fusion in their cores

the nuclear fusion reaction that occurs in stars. Page 294 Stars are made primarily of the almond hydrogen the most common material universe. As a star forms‚ gravity pulls the hydrogen into a dense ball that heats up. Electrons are torn from the hydrogen and other atoms‚ creating a plasma made up primarily of protons (the nucleus of the hydrogen atom) and electrons. Normally‚ protons would repel each other. As matter accumulates ending the new star however‚ the protons move faster as the temperature
