THE LIFE CYCLE OF STARS
by Naomi Doku, Shierla Sanon, Sanjay Brown
A star first begins to form with stellar dust. Nuclear fusion makes the stellar dust very dense. Gravity is the force that sucks the dust in. The star becomes heated and starts to glow. The star has a lot of fuel and it will become bigger and higher. If it does not have alot of fuel than it will be smaller and lower.
The proceeders of a star form on a dark gas and each core contrast as gravity pulls. Each energy speeds up the center of the core. The size, shape, and color of a star is fixed by its helium.
Blast waves or other disturbances cause clumps to form. Each core contrast as the core rotates, and the center collapse; energy of falling stars heats in the center. Temperature at center gets hot for nuclear reaction to start. As the star spins faster it flattens into a dist.
The new star settles. Turns hydrogen gas into helium, turns it into nuclear. Every shape, size is fixed by its mass. Forty times more massive than sun is twenty times bigger. Smaller stars are dimmer. Orange is 3/4 the sun's mass.
Five billion years ago the sun formed form a inner stellar cloud; then stayed as a yellow star. In 5 billion years the sun is going to run out of hydrogen. Next billion years, the sun becomes larger, brihghter and its structure is unstable. Star cores has different nuclear processes. Part of the core rebounds in a stock wave that blows the star apart. The star cannot compare to the brighest of the sun.
Double star is a half of a star that is held by pairs of stars fo its gravity. The swinging of waves move asround and moves the alter toward and away form us. Larger stars evloves fastes to become a red giant. Close enough matter comes off one to another. Larger star expands till they become coiled.
