Life of a StarStacia Deutsch and Rhody
Cohon Discover how stars are born. Find out why they die.
Introduction• Many stars use telescopes and
other tool to study them.• Scientist called astronomers
study stars and other things I the solar system.• Stars are found in the solar
system.
Spectral Classes• There are seven spectral classes.• The seven classes are class o, b,
a, f, g, and k• Cause EffectQuickly lose fuel put into
spectral classes
Nebulas• Stars are born inside of nebulas.• A big cloud with huge clumps of
dust.• When a nebula collapses a new
star is born to a galaxy.
Protostars• Nuclear fusion is key to a stars to
a stars birth.• Sometimes stars form in huge
clusters so its nebula is really big.• The protostar shoots off its gas
and jets through its protoplanetary disk.
Chp.2 Main Sequence of a Star• Some stars don’t actually
become a real star.• They become brown dwarfs.• A stars mass determines how the
star dies.
Eta Carinae• One of the most massive stars
found in the solar system today is eta carinae.• Scientist predict that that eta
carinae will only live one million years.• Eta carinae is highly unstable.
Parts of a star• The sun is just a medium sized
star.• The core is where the sun makes
its energy.• The corona is the collection of
gasses all around the sun.
Chp. 3 Death of a Star• A star enters its final stage of life
when it runs out of fuel.• A medium to small sized star
becomes a red giant before death.• A large star becomes a red
supergiant.
Red giants• Soon the sun the sun will
become a red giant and swallow the earth.• A red giant creates a planetary
nebula.• Its used up all its fuel and can no
longer produce nuclear fusion.
White dwarfs• White dwarfs are dead stars.• The emit very little light and are
hard to detect because they have no energy.• White dwarfs are so hot that
they still glow.
