Nicholas Kellogg & Annessa strickland Life of a star

Life of a star We can see the stages of a star. Even though are life's are much shorter than that of a human. At the end of a stars life it will most likely resolve in an explosion.

Life of a star Life of a star Step 1- The star is born into a region with a high density nebula. Eventually it will become a baby star.(Proto star)

Life of a star Brown Dwarf- is equivalent to a (preemie child) When it is born it is to small to be a star.

Life of a star Stage 2 - A place of matter will begin to heat up once it hits 15 million degrees it will start to form.

Life of a star A star begins to release energy which makes it brighter and able to shine. Then it becomes a main sequence star.

Life of a star Stage 4 Stage 5 The star will stay in the mass for about 10 billion years until it is fused to form helium. The core is now hot enough for the helium to fuse to form carbon. Then the outer layers begin to expand which begins to cool and shine less brightly. Now the expanding star is called the red giant.

Life of a star Nuclear fusion- Its supposively the energy source of the future. Fusion is what happens when two atomic nuclei are forced together by high pressure.

Life of a star Helium fusion is a kind of nuclear fusion when the nuclei turns to helium.

Life of a star Planetary nebula is a emission nebula with gas and plasma in it.

Life of a star A white dwarf is a small star that is made of electron- degeretic matter.

Life of a star A Black Dwarf is when a white dwarf becomes to cold.

Life of a star Nebula with high mass is the same as a regular nebula.

Life of a star A protostar with a high mass will also be the same as one with a little one.

Life of a star It is a big main sequence star nothing really changes.

Life of a star One of the biggest stars a example is the sun.

Life of a star A supernova is a high stellar explosion.

Life of a star A neutron star can cause gravitational collapse

Life of a star A black hole is when the force of gravity is so strong not even light can escape.
