Transcript of Red supergiant
Hydrogen and Helium
~ The Sun
The range temperature is 6,000 to 10,000 k.
~Van Maanen's Star
When a red giant throws off its outer layers, it forms a planetary nebula.
This is a dying star at the last stage of its life
821.3 million km.
The force on the inside is greater then the gravity pushing in
Carbon, Oxygen, Neon, Magnesium, Sodium, and Iron
~The Waterfall Nebula
This is the first step to a star being made.
Particals within a cloud form together by the gravitational pull. The increased mass causes more gravitational pull. Nuclear fusion then happens from the pressures at the core of the construct and sparks the earliest stage of the development of a star.
90% of the stars in the univers are Main Sequence Stars
Fuse Hydrogen atoms to form Helium atoms. Can range from a tenth of the mass of the sun up to 200 times as massive.
None have been found yet because no one can see them
Don't know anything about them, they are a mystery to the world
Over the life of this star, the pressure of fusion has balanced against the inward pressure of gravity. When the fusion stops, gravity takes over and makes the star tighter and smaller by the amount of pressure.
~OJ 287 Primary
Born out of clouds of dust called nebulae.
The size is 1.5 to 3 times larger then the sun
life cycle is shorter then a Main Sequence Star
Due to the extream heat, heave elements are able to under go nuclear fusion
When this happends, the supernova can become brighter then a galaxy
If a star in the Supernova fase collapse, it will turn into a Neutron Star
A Neutron Star is completly composed of neutrons
An increase of gravational pull when the star size decreases, will result in the core collapsing.
The luminosity range is .0001 to .001
White dwarf's are made of pure carbon. This allows white light to be seen due to heat left over from past fusion of elements.
A star that is 3 times larger than our sun can turn into a black hole.
The core collapses and keeps collapsing in on itself, and this is why it is called a black hole.
