Transcript of The Life Cycle of a High Mass Star

Step 4) Makes a Red Giant Overtime hydrogen decreases along with the amount of hydrogen fusion.
Size vary by the mass The Life Cycle of a High Mass Star What Is a High Mass Star? A high mass star is a star that is created in the core with gasses and expands out. By: Camille, Ashley and Tika There are 10 Steps of Life in a High Mass Star. High mass stars go through a similar process to low mass stars in the beginning, except that it all happens faster. Step 2: Fusion Reactions Step 1) Hydrogen by using Gravity Fusion reactions will occur when the temperature and density are high enough. The fusion will continue to fuse for a long time. Step 3) Continue Fusion Process The Sun is at this stage in life, Nuclear Fusion energy causes the star to shine. The radiation movies outsides of the core. Step 5) Uses Nuclear fusion to make Carbon in its Core. Gravity is used to collect hydrogen.
A cloud of hydrogen will begin to spin, when a cloud spins its called a protostar , its brighter then other stars Mass: A large number of people or objects crowded together Words With Stars Gravity: The force that attracts a body toward the center of the earth, or toward any other physical body having mass Words With Stars Density: The degree of compactness of a substance
Temperature: the degree of hotness or coldness of something (as air, water, or the body) as shown by a thermometer. Words With Stars Fusion: The process or result of joining two or more things together to form a single entity.
Nucleus: a central point, group, or mass of something Words With Stars Layer: one thickness or fold over or under another Words With Stars Step 6) Forms new layers as more fusion reactions begins The number of fusion reactions increase, making more and more nitrogen , carbon and oxygen. Step 7) Try to fuse iron nuclei. The star will collapse. Fusion continues until elements with atomic number 1-26 forms. on periodic table,those are all of the elements up to iron With the force of gravity, a high mass star collapses rapidly, to make 3 helium nuclei. One Carbon gas, and fuses itself to make a lighter nuclei to make heavier elements. Step 8)Explodes to a Massive-star Supernova. Element: Any of the four substances (earth, water, air, and fire) regarded as the fundamental constituents of the world in ancient and medieval philosophy Words With Stars Still , they collapse continues .Eventually it quashes proton and electrons together causing them to become neutrons. Gas: An air like fluid substance which expands freely to fill any space available Word With Stars Step 9: Remainings of a Massive-star Supernova Event This step forms a blurry nebula in space from the debris of the Supernova. The debris can become a building material for the other bodies in space, for example, Earth. Energy: power or ability to be active Words With Stars Conclusion: These are just some steps of a High Mass Stars. It's not an easy process to make a star that you see in the sky every night; its just one of those amazing things that is from space Sources http://astronomyonline.org/Stars/HighMassEvolution.asp http://imagine.gsfc.nasa.gov/docs/teachers/lessons/xray_spectra/background-lifecycles.html
