Stars, The Sun, and Star Constellation By: Timmy M. LaMotte 3rd period Project Star Constellations Star constellations are to tell which star is which Without a star constellations they will be hard to identify Example: the Three stars you would see in a straight line in winter are part of Orion Mythology on Star Constellations Canopus the lowest star to the Greeks Ancient poets identified the Milky way as the road of the gods Libra the claws of the Scorpion Babylonians and Greeks both identified five planets as their gods Pleiades was a seasonal sign to any civilization The constellation figures of the northern hemisphere are over 2000 years old. Name of Star Constellation Leo Gemini Cancer Vigo Draco Orion Andromeda Cassiopeia Libra Scorpius Pisces And many others Constellation Facts There are 88 constellations recognize Currently, 14 men and women, 9 birds, two insects, 19 land animals, 10 water creatures, two centaurs, one head of hair, a serpent, a dragon, a flying horse, a river and 29 inanimate objects The ancient constellation-makers probably meant for them to be symbolic, not literal, representations of their favorite animals or fabled heroes, a kind of celestial Hall of Fame Constellations (cont) There are obsolete Constellation Astronomers attempted to name them after patrons or kings These can be seen in antique star charts Almost every civilization had star constellations The big dipper is part of the Greek constellation the great bear Astronomers said that there where fixed stars which are permanent positioned in the sky Stars Facts Any star that changes is called a variable star they are usually Bright Stars can vary because intrinsic to the star itself Eclipsing binaries is a system where two stars orbit are inclined with each other so both stars will pass each other occasionally Pulsating variables stars are intrinsic they vary in brightness and is due with a physical change in the star Pulsating stars In the case of pulsating variables this is due to the periodic expansion and contraction of the surface layers of the stars or it increase or decreases in size periodically Light and curves show us the interior process in the star Cepheid light curves are distinctive and show a rapid rise in brightness followed by a more gradual decline, shaped like a shark fin Graph Of a Pulsating star To find the mass of a star This is the best way to find the mass of a star The sun Temperature The sun is the most hottest star temperature of 6,000°C (11,000°F) at the photosphere Its solar energy temperature is(15,000,000° C; 27,000,000° F) Chromosphere temperature 4,000°C (7,000°F) Sun facts The suns pressure is 340 billion times of earths air pressure at sea level A nuclear reaction can occur with protons and hydrogen nuclei to fuse together Its mass is expelled as energy because of convection Every second 700 million tons of hydrogen is converted to helium ash The corona is the outer part of the sun Sun facts (cont) The sun is 4.6 billion years old Has enough fuel to last another 5 billion years The sun will fuse helium into heaver elements and begin to swell up It will finally become a red giant Then collapse as a white dwarf Types of suns White dwarf Red giant Blue dwarf Shockwave Shockwave
