What dose a star start out with in the star life cycle.
Stars begin there lives of part of the nebula
A star begins to run out of
fuel
some materials may form a
nebula
The object that heat and light the planets in a solar system
other known as a star
all stars live by
hydrogen and helium
It is made up of gas and dust.
outer layers expand and it becomes
Red giant
when these stars begin to run out of fuel they become
red super giants
A star is is a ball of plasma held together by its own
gravity
at higher temperatures and pressures what can form
heavier elements can form
A Mature star gives off
light and heat
outer layers drift out in to space forming
a planetary nebula
the remains from the core may form a
neutron star
Nuclear reaction occur in stars
H-He
helium fuses with carbon can make
oxygen
the more the mass of the star it
buns out faster
The blue and white core cools and it becomes a
white dwarf
stars may explode any second this is called
supernova
energy from the nuclear fusion is released as
electromagnetic radiation
carbon and oxygen can make
silicon
A star is born when
The contracting gas and dust become so hot that the nuclear fusion starts
over billions of years it cools more and becomes a
black dwarf
what can also be in a neutron star
very small and dense,emits radiation and radio waves or remains of a black hole
what is a star
the object that heat and light the planets in a solar system
two silicn atoms fuse to make
iron
