What is interstellar medium
Gas and dust in space
What is the size of most dust
Microscopic
What is a nebula
Interstellar medium that collected into a cloud of dust and gas
This is where stars are born
What are stars made out of
Dust and gas
What is a protostar
A gravitational center that forms in the center and begins to pull atoms of interstellar medium toward the center
What is it called when A gravitational center that forms in the center and begins to pull atoms of interstellar medium toward the center?
Accretion
What must the protostar attain in order to become a star
Equilibrium
What is equilibrium
When the gravity pulling the atoms toward the center equals the gas pressure pushing heat and light away from the center
What stage is main-sequence?
The second and largest stage
What happens during main-sequence
Energy is generated in the core of the star as hydrogen atoms fuse into helium atoms
How long is the red giant stage
Short
Whats the stars first step into old age called?
The red giant stage
How does the red giant stage happen
The temperature of the star needs to increase to burn helium to carbon which cause the star to expand the star begins to cool because of the surface area as it cools it gives off a red color when its out of helium it will try to initiate the last fusion carbon to iron
How large will the suns mass be when the sun reaches the red giant stage
The orbit of mars
