Nebula theory
star
solar system
type of astronomical object
red giant
a large star
it uses up hydrogen and fuses helum into heavier elements
heavier elements that it creates in carbon and oxegen
has a gravitinal
its compressing the sun and the planets that orbit it
star formation
gas contenders to acer malate the material and it becomes more dense
galaxies
gas
H
HE
ICe
nebula
gravity #
cloud of hydrogen and hilum
fuse
high temp
low temp
that is left over from the big bang
there are also heavier elements that are trapped
gravity is pulling gas and dust
the more dense and pressure it has it increases the temp in the center and it becomes hot enough for the nuclear function
super nova
when the star has iron and its the only thing that is left
and it will also have gravity which will cause it to collapse
it will put a lot of pressure on which will cause it to explode
massive star
the star is a lot bigger
than a normal star they are usually 10 time or more massive than our sun
they fuse hydrogen into helium #
the outer layer spreads out and it cools down
the result is a cooler large star that is red in the color
white dwarf
it runs with helium and it will also try to combine with carbon
which will also cause it to go into a heavier element #
but it will fail and it will just expand away from the star and leaves behind the hot glowing carbon core which is called the white dwarf
black dwarf
when the white dwarf runs out of is energy
the back dwarf will get its remains when it loses its brightness
its 4.658 billions years old
