The Birth of a Star Kyle K Shane G Mark F
Interstellar Cloud The name given to an accumulation of gas, plasma and dust in our and other galaxies.
A Collapsing Cloud Fragment One of many fragments in a typical interstellar cloud that contains one or two solar masses of material. This fragment eventually collapses.
Fragmentation Ceases The fragment eventually shrinks to the size of a solar system and starts to heat up. This stage is when the fragment starts to look like a star.
Protostar 100,000 years into the stars lifecycle it enters stage 4. The protostar continues to shrink. –Its density increases –Its temperature rises
Protostellar Evolution In stage 5 the protostar has shrunk to 10 times the size of the sun. Its central temperature is approximately 5,000,000 K.
A Newborn Star The central temperature reaches 10,000,000 K which triggers nuclear burning. –This process causes the star to be born.
The Main Sequence Over 30,000,000 years the star continues to contract. Its central temperature reaches 15,000,000 K. Stage 7 is about where our sun is now.
Stellar Evolution Stellar Evolution Or How and Where do stars come from?
Stellar Evolution (of sun- like stars) How do stars age & die?
Evolution of Stars. Main Factor of Life Cycle Beginning mass.
Life cycle of stars Nebulae to supernova. Stars and radiation Stars are huge nuclear reactors that give off different forms of radiation (see below) all.
Life Cycle of a Star. Stage 1 Protostars Protostars Huge clouds of gas (hydrogen) in which stars are made. Many thousands of times bigger than our.
Notes 30.2 Stellar Evolution Std 2d: Know stars differ in their life cycles and that may be used to collect data that reveal those differences Std 2f:

Unit 1 The Universe Mrs. Williams 8th Grade Big Idea: The sun is one of billions of stars in one of billions of galaxies in the universe.
Protostars are difficult to observe because A. the protostar stage is very short. B. they are surrounded by cocoons of gas and dust. C. they radiate mainly.

Twinkle, Twinkle, Little Star.... How I Wonder What You Are... Stars have Different colors –Which indicate different temperatures Red stars- cooler White/blue.
Light year is: Distance that light travels in a vacuum in one year, about 9.5 trillion km - which is used to record distances between stars and galaxies.

Is There Life in Space?. How do scientists study the solar system? Telescopes Telescopes Radiowaves Radiowaves Infrared Infrared Visible Visible X-rays.
Stellar Evolution II. The Upper End of the Main Sequence: How massive can a star get? Larger clouds of gas (GMCs) tend to fragment into smaller ones before.
